Open Source Yoot Tower

AKA: SimTower from Maxis, The Tower, The Tower II, The Tower SP for Gameboy Advance SP, The Tower DS for Nintendo DS

Welcome to the Open Source Yoot Tower repo!

Yoot Saito just sent me (Don Hopkins -- don@donhopkins.com) a code drop of Yoot Tower for archival and academic study, and to make a modern open source version that runs in the browser!

So I’ve started the process of documenting and publishing the public open source version of Yoot Tower on GitHub:

https://github.com/YootTowerManagement/YootTower

Call for Collaboration

Anybody want to help, or know somebody who does, please? ;) You can get in touch with me at don@donhopkins.com.

Please check out the YootTower repo, where I'll publish the source code once it's cleaned up, reviewed and approved by Yoot, and relicensed with the MIT licensed.

There’s a lot of stuff, so I am going over the files, sorting out which versions there are, and trying to date and classify them.

Boy am I jazzed!!! It’s as cool as I imagined, even more!

Constructionist Education

Both Yoot Tower and SimCity/Micropolis share the same goals and benefits of constructionist education, inspired by Seymour Papert and Alan Kay.

Micropolis: Constructionist Educational Open Source SimCity

A lightning talk at HAR 2009 about applying Seymour Papert's and Alan Kay's philosophy of Constructionist Education to Micropolis, the open source version of SimCity. Illustrated and edited transcript of the YouTube video playlist: HAR 2009: Lightning talks Friday. Videos of the talk at the end.

LGR: Yoot Tower: The Sequel to SimTower

Maybe somebody can even fix the bug in the Windows version that Clint Basinger (LGR) kept getting zapped by in his in-depth review of Yoot Tower:

Micropolis Core (Open Source SimCity for the browser, using WebAssembly)

I’ve been getting a head start on porting Yoot Tower to the browser by working on renovating the existing open source C++ version of SimCity / Micrcopolis to run in the browser too, using Emscripten and Embind to wrap the C++ code in a JavaScript/TypeScript API.

Both projects will share the same modern tech stack and web interface (Emscripten, Embind, WebAssembly, TypeScript/JavaScript, SvelteKit, Node, Canvas/WebGL/HTML/CSS, etc), and I'm developing a JavaScript based SDK and plugin system for them both, so they'll eventually plug together with multiple Yoot Towers embedded into your live Micropolis city! And then you can plug a video arcade into Yoot Tower, which includes a Micropolis game console that you can play, to wrap back around to the outer city simulator! (No nasty infinite regression, just a nice clean loop!)

Emscripten MicropolisEngine Wrappers

This is where the magic happens that binds the C++ MicropolisEngine simulator class and structures to JavaScript, so you can call back and forth between C++ and JavaScript, and implement the user interface and plug-ins in JavaScript. See the comments in the code for a description of the approach and design considerations. We will take the same approach with Yoot Tower.

https://github.com/SimHacker/MicropolisCore/blob/main/MicropolisEngine/src/emscripten.cpp

Next Steps

I examined the timestamps in the files in the Yoot Tower code drop, and organized the sources and releases by date, translating the Japanese directory names.

The file names and function and variable names are all in English, but there are lots of Japanese comments, and some user visible Japanese strings that will need to be translated.

I'll continue comparing and analyzing the different versions to figure out how they changed over time and what to use for the open source version.

It includes the old Maxis SimTower code, some Japanese Windows versions, and versions for the GameBoy Advance SP and Nintendo DS.

The most recent version is the Nintendo DS version. It has some interesting additions and changes, but I presume a lot of that stuff is Nintendo's property and branding, like Mario and other characters we can't use in the open source version.

We have to remove / fictionalize / rename / rewrite / redraw any trademarked content for the open source version, but we can archive the original sources for academic research purposes.

Jeff Braun told me what happened with Maxis and Godzilla, so we will be careful to avoid stomping on anybody’s property:

"Maxis was sued by Toho. We never referred to the name Godzilla, our monster on the box cover was a T-Rex looking character, but... a few magazine reviews called the monster, Godzilla. That was all it took. Toho called it "confusion in the marketplace". We paid $50k for Godzilla to go away. In all honesty, Toho liked Maxis, they said $50k was the minimum they take for Godzilla infringement. I doubt you will need to worry about Toho, as long as there are no magazine reviews that call the monster Godzilla."

I guess the lesson is to always make sure to give your monsters a unique name, and don’t leave that up to the user’s imagination.

Thanks for your attention and any advice or collaboration you can contribute!

Introduction

This Open Source Yoot Tower repo encompasses the evolution and development of the "SimTower" game, created by Yoot Saito and later developed into "Yoot Tower" in the US and "The Tower II" in Japan. Published by Maxis, the game, initially released as "SimTower: The Vertical Empire" (or "The Tower" in Japan), is a construction and management simulation game for Windows and Macintosh System 7, developed by OPeNBooK and published in November 1994. It involves building and managing a tower, placing various facilities to achieve a five-star rating while dealing with random events like terrorist acts.

The Tower II introduced the Tower Kit an optional software allowing players to add new maps and stages, enhancing gameplay with new features. It also included a crossover element between redevelopment and a love story, set in New York. The game links to the movie "Gamera 3," featuring battles between Gamera and Gyaos in Tokyo, and offers a final showdown in Kyoto. Additionally, it offers a special package with maps related to the movie and various towerkit maps, enhancing the gaming experience.

Discussions on Hacker News reflect the game's impact and its innovative approach to game design, including its start as an elevator simulator and its influence on the gaming community. Yoot Saito, the game's creator, also worked on other projects like "Mario Motors" and expressed interest in open-source development. His relationship with key figures in the gaming industry, such as Satoru Iwata and Shigeru Miyamoto, is highlighted, showcasing the game's significance in the industry and pop culture.

Description

Maxis published SimTower by Yoot Saito, which later developed and published as Yoot Tower in the US and The Tower II in Japan, along with many plug-ins using Tower Kit.

SimTower: The Vertical Empire (known as The Tower in Japan) is a construction and management simulation video game developed by OPeNBooK and published by Maxis for the Microsoft Windows and [Macintosh System 7 operating systems in November 1994. In Japan, it was published by OPeNBook that same year and was later released for the Sega Saturn and 3DO in 1996. The game allows players to build and manage a tower and decide what facilities to place in it, in order to ultimately build a five-star tower. Random events take place during play, such as terrorist acts that the player must respond to immediately.

What's Tower Kit?

Tower Kit is optional software for The Tower II. In The Tower II, you can select the stage where you want to start the game using the concept of a "map." The Tower II package comes with three maps: "Shinjuku Subcenter," "Hawaii Diamond Head," and "Kegon Falls," and the "Tower Kit" adds these maps. By installing this tower kit, a new stage game will begin. Tower kits don't just add more stages. Each map has new features, allowing you to play a completely new game.

Please try the "Tower Kit" which allows for infinite variations.

A love story between you, the person in charge of the Liberty Island redevelopment project, and two men and women who are your subordinates. Your work will have a subtle influence on the course of your love life. The Tower II is the first attempt at a crossover between redevelopment and love, set in New York. What is the ending...?

About Yoot Saito

Yoot Saito: The original impetus was the SimCity event held around 1993 at the "Simulation & Gaming Society" event. I met Mr. Will Wright, who had just released Simcity. When I showed him The Tower under development in the event waiting room, he was so impressed that he recommended it to Jeff, the founder of MAXIS, the publisher of Simcity. I remember jumping up and down when I heard that there was something going on. Even after 15 years, I don't think I've ever experienced news comparable to this.

Yoot Saito worked on Mario Motors, a canceled DS game about building engines Posted 21 April 2018 by Jordan Devore

He also explained what it’ll take for a new Seaman to happen

In a talk about game design philosophy at Reboot Develop 2018, SimTower, Seaman, and Odama creator Yoot Saito revealed that he once worked on an unusual Nintendo DS game codenamed Mario Motors.

Saito told some heartwarming stories about his friendship with Nintendo’s Satoru Iwata and Shigeru Miyamoto, some of which he has shared before in detail. Back in the early 2000s, the three would have get-togethers in which they would “chat over tea casually” and talk about ideas for games.

“During one meeting, Iwata-san asked me a question: ‘Saito-san, what have you been interested in lately?’ I immediately understood what he was getting at, so I answered ‘sculpting chunk.’ Miyamoto-san said ‘huh?!'” (To help explain to the audience what he was referring to, Saito talked a bit about how things like watches, camera frames, and MacBooks are made. Sculpting objects out of metal chunks spoke to him and it was an idea he “really wanted” to make into a game.)

“This kind of sculpting is really appealing to a middle-aged guy like me,” Saito said.

“I explained this crazy idea to them and they really listened to me very carefully in complete silence, and finally said ‘that sounds interesting, let’s give it a try.'”

The concept eventually morphed into Mario Motors, “a game where you created engines.”

Saito summed it up as “shaving and sculpting out of a chunk of metal to make a cylinder [which then] decides the ability of your engines.” For part of the game he wanted to teach players how acceleration works in an interesting way and thought about having them blow into the DS microphone. “I scrapped this idea because this would cause children to get out of breath,” he explained.

Reflecting back on his meetings with Iwata and Miyamoto, Saito said “I really understand just how much they respected each other, and how they formed the two wheels that pulled Nintendo’s game business forward. They paid attention to me because they were always hungry for something new.”

As for why Mario Motors never moved ahead, Saito said “I can’t tell you why, but please guess.”

He didn’t have any formal announcements to make during the talk, but it seems as if he’s still interested in a SimTower-style game (he asked the entire audience to come up mid-presentation and look at a basic prototype on his iPad) as well as Seaman. For the latter, Saito would want it on mobile “without any endings for years” and that would require a sophisticated and nuanced AI engine that talks back to players. “Until that engine is done, I’m not going to create a sequel to Seaman, but I am working on that.”

Yoot Saito on Iwata, canned Seaman 3DS game Posted 15 July 2015 by Steven Hansen


Some words from Yoot

Canned fish

We’ve covered Seaman frequently throughout the years on Destructoid with overflowing hearts. And it’s under tragic circumstances that we get confirmation: Seaman 3DS was a planned project that fell through.

Original Seaman developer Yoot Saito wrote a blog post, translated over at Neogaf, reflecting on his relationship with the late Satoru Iwata.

I first met Iwata-san back in 1996, so it was a time before you would typically see him in a suit. It was at HAL in Kofu. I remember that he always carried around a Mac (PowerBook), which was quite rare in the games industry. I think that formed a bit of connection between us—a feeling that we shared the same interests. It was around the year after that when I saw him with a G3 PowerBook, which even I had hesitated to buy, and I remember thinking, ‘this guy really loves Macs.’

It wasn’t until a bit later that I got a chance to work with him. It was around the time when Seaman was taking the world by storm and I was really busy working on planning for the sequel and taking interviews and such.

Iwata-san got in touch and asked if we could meet, and he even came all the way out to the apartment I was renting in Tokyo to see me.

As anyone who has met him probably understands, Iwata-san always has this aura about him that makes you feel happy and at ease. When you’re around him, you just feel good, even if you’re talking about work. That day, Iwata-san wasn’t in his typical casual garb, but had donned a blazer that he didn’t look quite comfortable in. He handed me his business card and awkwardly said, ‘this is what I’m up to these days.’ I looked at the card and he had a title that named him as part of the Office of the President. He said that he had distanced himself from HAL (the company at which he got his start in the games industry) and was now helping out at Nintendo (HAL was under the umbrella of Nintendo).

‘I’ve been given a special assignment to go out and get new types of games that haven’t been on Nintendo platforms before.’ That’s the reason Iwata-san gave me for why he wanted to meet that day. He told me that Seaman was the kind of thing he was looking for. Thinking about it now, his role at this time was probably given to him as preparation for taking over management of Nintendo down the road, but it didn’t look like that was on his mind at all at the time.

It’s worth reading in full for the interesting tidbits, such as Saito’s confirmation that his suggestion led to the Wii controller’s speaker, or Saito and Iwata’s experimentation with StreetPass sort of technology back in the Game Boy days. I was so bright eyed over the sincerity and passion of this nostalgia I almost forgot how Saito’s blog post had to end.

When Iwata-san came to ask me to create Seaman for the 3DS, I like to think he was in the same frame of mind as when he first came to visit me at my apartment back in 1999. I did start working on the project, but things got really complicated and I eventually let go of it. Unfortunately that brought an end to our relationship, where I could just casually visit him in Kyoto and have fun exchanging new ideas. I felt like we needed some time before we could go back to the kind of creativity-filled relationship.

It was early last summer that I first heard about him taking some time off to recover from an unfortunate illness. I distinctly remember it, because I was actually sharing a taxi at the time with two super famous people: Yuji Horii-san of Dragon Quest fame and Takafumi Horie, otherwise known as Horiemon.

Iwata-san, when I later saw you appear before the press, I was really happy to see that you had recovered, but it looks like the gods aren’t that lenient… Tezuka-san (from Nintendo) suggested that I make an appointment to see you, but I couldn’t find the nerve to do so. Now, after all my hesitation, I’ve learned that we truly passed each other by, and I’ll never be able to see you again. I wish I had a StreetPass feature that could connect with heaven. I would run out and buy a DS with that feature right now just so I could send you my thanks. Yeah, I know that sounds a bit too convenient for me. When I left the Seaman project, I sent you a book and a letter. Whether you actually read them or not has been on my mind ever since. Also, I’m really sorry for being late with Odama, causing it to completely miss the window for it to be a success. There’s so much more I want to tell you, but I really don’t know what to do with myself after hearing about your sudden departure in the news.

Life is always just a succession of regrets.

Iwata-san, thank you for everything. I don’t typically look up to a lot of people, but I really respected you. I would always be thinking from afar just how amazing of a person you are.

岩田さん、ありがとうございました。そして、さようなら。[Yoot]

Words from the Gamers themselves (Shocking)


Somewhat of a competitor, but any Sim Tower fans here? I was obsessed with everything Sim* but especially loved Sim Tower. Maxis was an amazing gaming company and actually my first entry into Macs. My friends dad had a Macintosh II, then classic, then LC, and I would spend hours playing games on them -nodesocket on March 17, 2017


Interestingly, SimTower was published by Maxis but developed by OpenBook (later Vivarium), the Japanese developer that would later make Seaman for the Dreamcast. -xxr on March 17, 2017


Yoot Saito just presented a classic game postmortem of "Seaman" at the recent GDC.

http://schedule.gdconf.com/session/classic-game-postmortem-seaman

Unfortunately I wasn't there to see it, but I saw him talk earlier about Seaman at GDC 2000, and it was fascinating to learn how he was able to pull off such an unprecedented original design, even supporting speech recognition on the Dreamcast!

Announcement: Yoot Saito is coming to GDC 2017 to present a Classic Game Postmortem of Seaman!

http://www.gdconf.com/news/yoot-saito-coming-gdc-2017-present-classic-game-postmortem-seaman/

"Yutaka "Yoot" Saito, the talented game designer known for his idiosyncratic approach to game development, will be delivering a Classic Game Postmortem on his remarkable Dreamcast game 'Seaman' at GDC 2017! Saito's game development career took off in the early '90s when he created the game that was published by Maxis as 'SimTower', but it was after he founded his own studio Vivarium that he really came into his own. Under the Vivarium banner, Saito developed the groundbreaking virtual pet game 'Seaman' (lending his own face to the titular Seaman), its striking sequel 'Seaman 2', the pinball strategy game 'Odama', and the airport baggage management puzzle game 'Aero Porter'. Now, Saito is coming to GDC 2017 to speak at length about his work creating 'Seaman', a game that left an indelible mark on the fabric of both the game industry and pop culture at large. Don't miss it!"

I just found the video of his GDC 2017 talk: Classic Game Postmortem: 'Seaman'!

SimEarth really taught me the importance of critical mass. You could peter out if you didn’t marshal your resources to reach the next stage of the game.

Oxygen Not Included is my simulation game of choice atm. It really punishes you if you don’t realize how quickly you’ll deplete some finite resource. -milesvp on May 19, 2020


Interestingly, SimTower was not developed by Maxis but by the Japanese OPeNBooK, and was originally released in Japan as "The Tower". Maxis then published it in US as part of the Sim series.

OPenBooK went on to develop Yoot Tower ("The Tower II" in Japan), a sequel to the original game, in 1998.

Looking at their Wikipedia page ( https://en.wikipedia.org/wiki/Vivarium_Inc. ), seems Seaman and Seaman 2 were also theirs - interesting.

As aidenn0 said, this sounds like SimTower and its sequel Yoot Tower.

Maybe Sim Tower? The game was pretty boring, but building and managing elevators to keep people happy was a fun challenge. -aidenn0 on June 12, 2021


Sim Tower and Sim Ant were both great network-building games. They seemed boring until you really delved into the details. Maxis was really genius up until EA bought them. Here's a pretty cool project they did that never came to light...

Here are some old Sims design documents:

This one describes Maxis's philosophy of Sim game design:

https://donhopkins.com/home/__/TheSimsDesignDocuments/MaxisSimRules.pdf

MAXIS SIM GAME REQUIREMENTS

SUMMARY

The Maxis marketing department recently studied customer expectations of Maxis Sim games. The study revealed seven descriptions of what the Maxis Sim player thought a Sim game should be. While the “Seven Points of Sim” descriptions reflect customer expectations, they are not all necessarily the ingredients for a Sim game. To understand why Sim players perceive Sim games the way they do, we can look at the key factors that make a game a “Sim”.

REQUIREMENTS FOR A MAXIS SIM GAME

Dilemma

Players must always grapple with difficult decisions. In SimCity, pollution may be a problem, but there might be a strong industrial demand. In SimTower, condo-dwellers will need elevators heading down, while office workers will need elevators heading up.

Crisis

Crisis can also mean disasters. Players occasionally need to abandon long term strategy in favor of short-term success. If a fire is burning in SimCity or SimTower, players might need to destroy all their creations in the surrounding area.

Budgeting

The amount of funding a player has acts as both a limiting factor and a kind of score. Every action by the player costs money - even mistakes - and there are no refunds. “Cheats” to gain more money are the most popular cheats.

Aesthetics

Artwork is important for players to admire their creations. Also, the ability to place buildings, zones, crops, etc. in various places that may not have relevance to the Sim, fakes players into believing that their city or tower designs are “better” than other’s. Finally, aesthetics are a form of reward for the player. In SimTower, an aesthetic reward for reaching the 100th floor is the ability to place a cathedral. This is akin to “winning”.

Change in Rules over Time

Rule changes cause players to change their playing strategy. In SimCity, demand for Industry is high at first, but then swings to Commerce. In SimTower, the placement of condos is important at first, but nearly irrelevant after the 3rd Star.

Visual/Graphical Feedback

A Simulator is nothing but formulae operating on a data set. The player’s main interpretation of the change in data is graphical, in the form of tall buildings in SimCity, and long elevator lines in SimTower. An example failure in graphical feedback is Outpost from Sierra, where player feedback is in the form of numbers in a dialog box.

Cause & Effect are not Immediately Apparent

Because of the interleaving data sets in the simulators, players may not initially understand why certain actions have unexpected effects. One of the compelling reasons to play is to discover and understand various causes and effects.

Players are allowed to destroy their Creations

Who says there is no violence in Sim games? A favorite activity of the Sim player is to save a “masterpiece” copy of their creation, then unleash disaster after disaster, and bulldoze like crazy.

So how long before they can predict the future to be at the right place at the right time every time?

It's certainly how interesting how critical a good setup can be to get a large skyscraper to actually work well. If they take too long to get to the people waiting then they need to leave or get to work. The old game SimTower is actually a pretty decent simulation of this kind of effect (if not still overly simplified).

-simcop2387 on Aug 6, 2012


SimTower was /actually/ just built around an elevator simulator. "You guessed right," she said. "Sim Tower was built around a real elevator simulation program we bought from a Japanese guy."

SimCity and Cities: Skylines are still half stuck in 1950s era car oriented urban planning so they're not totally representative of the real world and modern urban planning. In these games public transportation options are limited, walkable public spaces such as pedestrian only streets and squares are not possible, and bike lanes do not exist. Additionally zoning is either residential, commercial or industrial, so there's no concept of mixed-use zoning (ie. commercial on the bottom of a building, residential on top) which you see everywhere.

I'd love to see a smaller scale game that really focuses on these details. SimCity 4 and other games went in the other direction, building systems around how a metropolitan region of multiple cities would interact.

-rmserror on Aug 7, 2012


SimTower sort of did this, within the context of a single skyscraper. I'm not sure if it is on GOG or anywhere else legitimate these days - odds are it might not be a simple matter to run on modern Windows, unless you want to spin up an XP VM.

I spent way too many hours playing SimTower as a kid. It was pretty fun, especially if you took advantage of the infinite money cheat involving building a specific type of room in one certain place on the bottom of the level... Not bad for a game that was built around an elevator simulator

I've very much enjoyed playing SimTower, and I still have a legitimate exe of it sitting around. But the game is a Win16 game, and my latest experience running it in WINE was crap (it became very easy to completely lock up X). Possibly it might make more sense running in Windows 3.1 in dosbox.

Incidentally, this is a motivation for why I'm playing a bit with statically recompiling x86-16 code to run on x86-32.

If I remember the story correctly, the creator of Sim Tower wondered the same, and discovered that the algorithms governing that were closely-guarded secrets. So he developed Sim Tower.

So, somewhat related. Is there a way to play Sim Tower nowadays? I regret that I never got that last star, and think about it once or twice a year.

Try https://infinitemac.org/

Pick a System Software/Mac OS version (you probably want something like 7.5), then choose the SimTower disc from the CD-ROMs drawer at the bottom of the screen. -brirec 23 days ago

algorithms governing that were closely-guarded secrets

Do many lifts have fancy algorithms in practice? I don't think I've ever had one go backwards to pick up a nearby floor, for example.

I suppose optimising where the lift loiters while empty is something I wouldn't really notice happening.

I am not sure how you derived that conclusion from the article. The passage seems to imply little else than a company spokesman declined to divulge proprietary information to some random dude who cold-called them.

I know Yoot Saito (creator of SimTower) from my time at Maxis, so I just gave him a cold call out of the blue and asked. ;) I caught him drinking Jack Daniels in a Japanese bar, but he had some time to chat.

He said he once did a big interview with BBC about SimTower (which would be worth looking up and watching if you can find it), and had a friend who worked in the elevator industry, who told him generally about how elevators worked, but much of it was secret and proprietary, so he had to come up with how they worked in the game himself, based on the general ideas he learned and his own experience and imagination.

He also said he's interested in releasing the original source code of SimTower as free open source software, like I did with the original SimCity Classic source code, so I volunteered to help him and find other people who could help. Anybody interested? ;)
