They are making SteamOS compatible with other hardware, if you want to build a steam machine of your own. Also their contributions to Wine and Fex will enable other Linux gaming platforms that are not SteamOS to have the same compatibility layer.

At every all-hands meetings, core team gets to present, gets to showcase the new features, gets celebrated for "going the extra mile" for customers.
But the real extra mile, is the patience, empathy and thoughtful communication (which is a rare talent, really) of the entry level engineers, who are also humble and nice to be around with, being the only ones who contribute positively to the company culture, as opposed to the ego-tripping 10x engineers.
Management thinks they are absolutely replaceable. Even more, when the concept of "AI agent" appeared on their radars, they were the first people who they thought they're gonna replace.
But the real reason to replace them is to please investors who don't wanna be behind the AI-efficiency-hype. They can't be promoted to a core team, because where's the efficiency in that?
What I didn't like, is the tutorial is separate from the game. It would be awesome imo, if there's a tutorial stage where the game is explained hands-on (maybe pausing the game with explainers, until I start to get how to play) Otherwise I have to memorise the instructions before trying the game.
Regardless, amazing little game.

I also asked claude to give me a 1-paragraph summary of how our stack works. Anyway, if you have more questions i'm happy to answer e-mail (check my profile)
Robotic text below:
The whole thing is TypeScript end-to-end, run by Deno, which acts as the glue. In the browser, there are just two pieces communicating over a native WebSocket: a React front end bundled by Vite—Deno runs Vite for the development server and hot reload—and a Deno back end that owns the simulation.
The simulation runs on a tick loop, with each tick representing roughly one in-game day and taking about one second of wall-clock time. The client sends small command events such as `newBuilding` and `bulldoze`. The server processes each tick and broadcasts all resulting state changes in a single batched frame. This makes the client essentially a renderer of authoritative server state, with a full resynchronization whenever it reconnects.
Under the hood, the simulation distributes heavy workloads—including demographics, taxes, and housing markets—across Web Workers. These workers coordinate through a shared SQLite database used as a cross-thread bus, allowing the game to simulate tens of thousands of citizens.
The 3D layer uses Three.js with WebGPU, a WebGL2 fallback, TSL shaders, and batched draw calls. It runs imperatively in its own `requestAnimationFrame` loop inside one large component, deliberately avoiding React Three Fiber. React manages only the 2D HUD and menus layered on top, keeping the performance-critical rendering loop entirely outside React’s reconciliation process.
The key point for prototyping is that the browser application—the client plus a local server connected over WebSocket—is the entire game. The desktop builds are simply thin native shells around the exact same application. On macOS, the shell uses Tauri with Rust and the operating system’s WKWebView. On Windows and Linux, it uses Electron with bundled Chromium.
Each shell launches the server, compiled into a single self-contained binary using `deno compile`, as a sidecar process. It then finds an available localhost port and points its webview at the bundled client. This means the game can be built and iterated entirely in the browser, with native packaging added only at the end.
For Windows, it was a bit less dramatic, but WebView2 is controlled by Windows Update in Windows 10, Some players have it, some players don't. And requiring windows 11 and up is a very unpopular choice. Maybe could have been solved by vendoring it but also not super clean.
I look forward to give it a try again, when Steamworks Linux runtime 4.0 comes around, and less people are still using Windows 10.
My city builder game, Microlandia[1], runs on Deno. The game's graphics and UI is a Three.js/React app, but the guts of the game are in a "sidecar" process that is a `deno compile` typescript executable.
On Mac, there's a Tauri shell that runs both client and server, and for Linux and Windows we use Electron, (Tauri proved to be quite problematic except when in macOS)
Why on earth did I choose this cursed stack instead of a "proper" game engine? Well,
Turns out developing the simulation in typescript with a performant sqlite driver hot reloads very fast and with a light code editor and my browser open on a second window I see the stuff updating live as I make it.
Deno has a good VSCode extension with test helpers and a fast language server. WebGPU is good enough for me to write any cool shader I can think of and I don't miss any capability of a game engine.
More importantly, not using Unity/Unreal brought back to me the joy of game development that I had lost due to and horrendous UI-driven workflow that takes me back to Macromedia Flash (yes, I am that old). Oh, and the licensing.
And I know I could switch to Bun with small changes in code but Deno has never got in my way. Maybe it's because I avoid using libraries at all costs (and don't need much).
Also, Typescript/React is such an amazing language for building a complex tycoon/simulation type of game that deals with a lot of data and displays it. Anyone who's worked on Unity knows it's the dark ages for UI over there.
I'm unsure if i'll port the game to Deno Desktop anytime soon but if I start a game again I will use this stack again, as my game engine, this time without Electron or Tauri.
Like Elon Musk, who once wrote in a company-wide email in 2018: "Walk out of a meeting or drop off a call as soon as it is obvious you aren't adding value"
I'm guessing the decision is about making a online leaderboard?
I want it to come back because it's in the spirit of the game not to hide the "ugly" aspects of city life.
There is gentrification in the way that landlords discriminate low income renters and NIMBYs have political power over you (in the form of the 'disagreement aura')
There's no rules against building single family homes in a city center, but the effect is what you would expect: non optimal tax revenue as you could zone it for something that's worth a lot more.
Regarding the unit economics for finance sector, you are right, the calculations are way too simple, and I'm not entirely happy with it, so I'm looking to improve it, but it does need to be a sweet spot between 1. realistic enough to be educatioal and 2. simple enough you can use it as a gameplay mechanic.
Before the end of the year there will be mod support, and I will pay special attention to making sure that modders can swap the economic formulas for more sophisticated models.
Not difficult at all. Pay the fee, get something going.
> Are there any artists you'd recommend working with? I need a 3D/Blender artist, especially.
My e-mail is on my profile, happy to send a few intros your way.
I like the landing page.
I'm currently working on modeling energy, climate and new policies like universal basic income
So there is a bigger incentive to run locally something that's gonna get you $20 or $100 worth of bills to OpenAI than to mirror something that is actually free.
Example: In the past there was a whole market for sound cards, if you wanted your computer to have any "multimedia" capabilities you needed to get a sound blaster but now everybody assumes a computer will produce sound, and it's basically for free as all chips have it. Now sound interfaces are still a thing but only for audiophiles who are esoteric enough like me to believe that it's worth to have that extra hi-fi quality.
What I think it could happen, is that eventually AI will be part of all the chips, just like soundcards. And there will be people who will buy specialized AI from companies that perhaps are not OpenAI or Anthropic but second-generation sleepers who watched the carnage in the market and decided to enter when it was reasonable.
This could be Apple, or Nvidia or something new. They're just waiting for the others to do the research and introduce the taste for it to the masses, just like sound blaster made us fall in love with high fidelity sound in our computers.
