Why Roller Coaster Tycoon is a Game Development Masterpiece

[@JuniorDjjrMixMods]

Just a little curiosity to get an idea of the absurd level of optimization that this game has: Each trash bin in the game only uses 2 bits to calculate if the bin is already full enough. How? Simple: the first bit indicates that some litter has already been put, and the second bit has a chance of 1 in 255 (iirc) to be set every time a new person places litter there, if both are set, it is considered full. So it will be considered full, randomly, after second litter. Yes, he could have used, for example, 4 bits to count a value from 0 to 15, but he still insisted on doing all this to save 2 bits of memory.

[@jasonhildebrand1574]

And this is more realistic, since you never know what, or how much trash each person will put in the bin.

[@laszloposzmik5829]

I wish i could see this level of optimization in today's games. Many games consumes drive space enough for 100-150 CD's. A save game could be 5 - 100 MB.

Even using the most advanced tools from today, making a game with the complexity of TTD or RCT as a single developer would be an astonishing accomplishment.

[@Spinexus]

I don´t think people understand how deep this game goes. He made somewhat realistic g-forces for roller coasters which gave you penalties if their lateral Gs, positive or negative vertical Gs are too high. For example if you build an unbanked turn following a big drop the game somehow knows that the lateral Gs are over 6 and you get a penalty which means people are less likely to ride it. If you do too much crazy stuff the guests will say "this ride looks to dangerous" and they wont use or pay for it.

He was also contracted to do an enhanced port of Elite to MS-DOS in 1991. The publisher budgeted for two floppy disks but Chris fit the game on one, so they still shipped both but the second one ended up being a blank just for storing save files.

[@gregorymoore2877]

You mentioned RCT had one graphic designer and one composer. Their names are Simon Foster and Alistair Brimble. I believe Simon did the graphics and Alistair did the music, but I might have that backwards. I don't know that I would say the game was completely bug free, but I do recall it was extremely rare for me to encounter any bug. RCT2 did reuse the graphics from RCT, but it felt like a little bit more than just an expansion pack. RCT2 included many things that were wished for in the first game; like extra flat rides; new types of rollercoasters; the rollercoaster designer and scenario editor; and the ability to have sloped curves with banking. Of course, RCT2 itself did have two expansion packs, Corkscrew Follies and Loopy Landscapes. Later releases of RCT2 have the expansion pack stuff included.

[@reaganharder1480]

RCT2 had more than just those 2 expansions. I know because as a child I was gifted one, Wacky Worlds. Most of the new coasters seemed to me to be basically reskins of other coasters already in the game, but the new scenarios were fun and anyway reskinned coasters isn't all in all a bad thing. And yeah, as far as RCT2 being just an expansion of the original, I can see how the argument could be made, but as an expansion it would be huge. The number of new rides with different mechanics to play with, a few new core game features like you mentioned with the rollercoaster designer and scenario editor, new scenarios... Like, in my mind, for in-game content, RCT2 more than doubled what RCT had to play with. And let's not underrate how iconic the music in that game is either.

[@xeridea]

A big reason for performance difference at the time was that compilers weren't anywhere near as good at optimizations. Compilers these days are vastly improved, making it difficult, if not impossible in many cases to get any performance benefit from assembler unless you have an deep understanding of how CPUs work, and knowledge of the vast array of tricks compilers use. Generally the best you can hope for is equal performance to an optimized C or C++ program. Most all the tricks people use in ASM to get better performance are baked into compiler, and also many more that would be highly tedious for programmers to implement manually, delving deep into how they actually do math to take some very clever shortcuts, as well as being much easier to use advance features such as use of SSE and other CPU intrinsics. Compilers us them even in basic loops if it makes sense to do so. It is worth noting that the SNES supported use of C, but no one used it because compilers at the time were pretty terrible performance wise, making it realistically unfeasible.

[@superblaubeere27]

AutoVectorization does not work too well on all problems, sometimes it is the best to write the SIMD assembly code for that by hand

[@xeridea]

@@superblaubeere27 you can do the intrinsics in C. There are libraries to make it easier to work with, so you don't have to manually do all the boilerplate stuff. It is sometimes possible to beat the compiler, but it is generally not worth the effort, except for certain tight loops and performance critical apps. Back in the day, it was fairly trivial to do better than the compiler. There are still programs done in assembly, it will never go away, it is just used less.

[@dhkatz_]

Yeah a lot of people don't seem to understand this. You would be stupid to attempt this now. It's funny because if he had written the game in C/C++ it would probably perform BETTER today if it were recompiled with modern compilers. They would for sure beat his hand written assembly. Obviously for its time it performed better than the compiler could do though.

[@Chaosman88]

Thanks for clarifying that. I was thinking that writing an app in Assembly nowdays would be worth the effort because of the performance boost. But now that you mention that the compilers are so optimized, you saved me from a lot of trouble :)

[@NYKevin100]

@@dhkatz_ It hardly matters if a hypothetical C version would perform better, since the original performed fine on the consumer hardware of the 90's. On modern hardware, both versions would probably run at an unreasonably high framerate, far beyond what your monitor is physically capable of displaying, so there would be no noticeable difference in performance anyway. The real benefit of a hypothetical C RCT would be portability to non-x86 architectures (i.e. the mobile ports mentioned in the video would've been much cheaper and easier to make).

Not to mention, with out some adapters, you can't plug in a cartridge for a Commodore 64 or an Atari 2600 in you PC now, and even then you still need a emulator for that. The point is, its rare to find a game made for some older PCs that work on modern hardware that runs on it's own with out a emulator or searching for a solution online.

Transport Tycoon is massively underrated, it's really one of the best games of all time.

[@cl8733]

Definitely! And the OpenTTD community is great, making the game worth while even today in 4K.

I don't think it was underrated. It was quite famous back then and still has quite a number of players.

I think the reason is that people just do not understand how train signal works, or logistic in general, as the game is pretty realistic in concept of how train route works. The game is too challenging and intimidating, people still ask how basic signal block signal works online. lol And OpenTTD took it to another level of depth, I am still playing it today.

[@WackoMcGoose]

Another game dev I'd put on the Sawyer Tier, is Tarn "Toady One" Adams, formerly-sole developer of Dwarf Fortress (his brother did do some work on it, and he's brought on an additional dev for the Steam release). DF isn't written in raw ASM, but the simulation is _far_ more complex than RCT's elaborate but still ultimately numeric-abstraction-filled parks, despite being tile-based, nethack-like ascii graphics. Combat damage is simulated down to _individual layers of tissue WITHIN individual organs inside a body,_ all sentient creatures have full backstories and personalities and interests, you can watch civilizations rise and fall then spend literal days looking through the highly specific and detailed generated lore of a world... It's crazy how much the game is able to do in an executable of mere megabytes.

It's amazing to know the amount of detail it has like people will be afraid of certain rides and bored of others even in case of custom designs. So basically a logic to evaluate this factor was also coded possibly in assembly.

Honestly this is is bullshit, RCT3 is beloved by the community. Locomotion on the other hand totally bombed and is not at all liked, hence almost everyone plays OTTD, while Locomotion only now got an open source version.

We hate Atari, for the sins they've committed. RCT1-3 are beloved by fans of rct. Devs of RCT3 went on to make planet coaster if I recall correctly.

RCT3 is trash. It has a ugly soulless artstyle. Maybe the gameplay itself is fine, but this new look makes it so hard to create something nice. In RCT1 And 2 building a prebuild wooden coaster and a few trees was enought.

Amazing documentary. And just... WOW, Chris Sawyer, what a legend. RCT is definitely one of the best games ever, and being #1 and #2 in such a competitive market, in which game sales were driven mostly by the real quality of the game (especially but not exclusively game design) and not because of big budget marketing, endless sequels or use of IPs is crazy.

[@rayromanov]

Chris Sawyer had such an immense impact on my childhood with first Transport Tycoon and then RCT. They're still my favorite games to this day (as OpenTTD and OpenRCT2). An absolute legend in the game industry, and a madman for doing it all in assembly all on his own.

[@perodactyl490]

My favorite type of assembly is 6502 (or 65c02, they're practically the same) Some things listed involving many lines of assembly for one line of C annoyed me because, for example, a loop needs a condition which needs to be determined every iteration, you need to store the index, and you need to repeat. Or a function. All it does it push some data to the stack to remember what it was doing before the function, and then it runs the function, and then it pops the data. It's helpful because you know exactly what you are telling the machine to do. No strings attached.

[@critical_always]

Wow, sounds like he does deserve this brief moment in the spot light. He sounds like an awesome guy. I hope he got compensated adequately for his work.

[@rawbmar1166]

When you're the one doing all the work, you get more than the average developer.

[@rubenvanbelzen1217]

Man I could not agree more with this video. RCT is my childhood’s favourite game, and I still play it occasionally. One thing that I have taken away from this video is that Chris Sawyer was so humble, by not having microtransactions in his game. Even Minecraft Bedrock on the phone has these! This has only increased the respect for this man

[@perprerp]

I spent so many hours playing Transport Tycoon. I admired how complex and performant that game was, without having any idea it was developed in ASM and by a sole developer. It also had a great MIDI soundtrack. Thanks for making the video!

[@jayjaynet]

As you said, this game is a masterpiece. I didn't know that TTD and RCT were made in ASM and by a single guy. Currently I'm work as a ASM Programmer (Z Architecture) and even though I can't imagine how he managed to did it alone.

[@maxave7448]

Thats really cool imo. For me, I made a hello world program in x86 assembly and thats where I draw the line. I have a question though: why cant you use C? 99% of the time the C compiler can generate assembly faster than anything a human can write and has some pretty insane optimizations and is also a lot easier to read, so why not just use that? (unless you are working with legacy code, in which case you probably have to stick to asm)

[@jayjaynet]

There are at least 2 reasons we use ASM here. Performance and access to hardware features (at least when the system was developed, some features were exposed just for ASM programs).

Makes me a little sad in a good way to know he wanted to keep pricing as it was when I was young. I have slowly fallen out of gaming over the past decade. But recently I was looking for something simple I could pick up and put down when ever. Found this RCT Classic on the app store. Then looking at a few tips and tricks on youtube I saw a short about this guy, Chris Sawyer, probably your short. And that made me watch this vid, because of the YT SHORT intro. I get sad thinking of the benefits of the past. Games had cheats and exploits. You could play for years and get better with weapons, really learn the game. Unlike warzone, they keep switching stats. I personally feel it's messed up, constantly tweakinga game for profit like warzone. But if you grew up in that world of the games constantly being altered, would you also develop better adaptability skills? Anyone born past 2010 have any thoughts on this? Would anyone that age even be watching a video like this. I'm interested in young culture and their world view. Just like how I wonder how older people view me in society. Are we really having the same experience as they did. And if not, how has this affected me differently.

[@superultrathanksmom3845]

It looks like in two months no young person has stumbled across your comment. I'm in my late twenties and I grew up with this game so I can't answer your question. What I can say is that even though there's horrible triple A cashgrabs now there's still plenty of mindblowing gems being made and there are lots of kids playing very good games, and they can access all of the old classics easily as well! Though it has certainly become more of a grim and exploitative world, which could be said about civilization as a whole I feel like. Games like Roblox and many mobile games are often terrifyingly designed to get kids hooked on microtransactions and gambling mechanics. I wonder if the claws of capitalism will ever lose its grip on humanity...

[@dophie3292]

I'm 25, Roller coaster tycoon 2 was one of my childhood games but not really this. In high school our big game was league of legends which was constantly updating.For us it was cool it just means you have to playing consistently to keep up with other players but it also means that the game has a long lifespan and always feels fresh. League the main game me and my friends played all through high school so about 6 years of playing consistently every week Now that im a bit older i tend to look for games that dont take so much of a comittment but I defintely look back on those years of playinge League with my friends and family fondly...

[@Gameprojordan]

If you're interested in playing off a PC look up "OpenRCT2" it's an open source version of the original RCT2 with a lot of extra content, and the ability to easily download and install mods into the game.

[@fusrosandvich3738]

I'm a 2000's lad, but i've found that Triple AAA games are basically complete garbage and should be disregarded. Anything made by AAA developers is almost universally terrible with very very few exceptions. Capcom seems to be the only one left who's focus is "make fun video games". You should always go indie when buying games nowadays.

What an absolute unit. I love assembly. It really teaches you a lot. I wonder if the C compiler would get better performance. Maybe not at the time, but today they probably would.

The compiler still makes redundancy code because c is much more abstract.

The compiler transforms code in assembly, how would that be faster?

Visual C 6.0 would've optimized for the Pentium but you'd just be running twice as much code twice as fast.

@@Nocfairy because compilers can find extra efficiencies when converting from C that you might not think of when writing asm. Professors troll college students students on that all the time. I mean, the game is so efficient it’s probably silly to do a test or something.

One great thing about RCT that set it apart from other themepark games is that all the ride were based on real world rides that you can find all over the world (yes people the Steeple Chase is a real coaster, it's at Black Pool Pleasure Beach in the UK)

I just want to add, that assembly is rarely faster than compiled C/C++/Rust code today. A lot has happened since the 90s and compilers are usually able to produce better machine code than humans.

Also the way CPUs work has changed quite a bit. Obviously there's parallelism, but also branch prediction means it's sometimes better to do the predictable, but slightly less efficient feeling thing.
