Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Voronoi, Manhattan, random
Bevy. A very young engine where you need to write the game entirely in Rust—that was appealing. But fatal flaws overshadowed everything: no editor, the engine brutally enforces the ECS approach, and the game's architecture must literally bend to fit this paradigm. So, you won't migrate to another engine at all—you just throw away all the code and start from scratch.

Web Game Engines and Libraries
Missing one of the best choices as long as "maturity" isn't on the top of your list: Bevy - https://bevyengine.org/
Game engine written in Rust, leveraging ECS in almost every place and way, with a really capable WASM export option. Wrestling ECS for the first time might take you some time, but in my experience helps you keep game code as clean and decoupled as game code could be.

3D and 2D: Testing out my cross-platform graphics engine
I don't see WASM/WebGPU changing anything when it comes to gaming, as an industry, personally. 3d visualizations and interactive websites? Yeah definitely a nice improvement over WebGL 2, if years late.
WebGPU is pretty far behind what AAA games are using even as of 6 years ago. There's extra overhead and security in the WebGPU spec that AAA games do not want. Browsers do not lend themselves to downloading 300gb of assets.
Additionally, indie devs aren't using Steam for the technical capabilities. It's purely about marketshare. Video games are a highly saturated market. The users are all on Steam, getting their recommendations from Steam, and buying games in Steam sales. Hence all the indie developers publish to Steam. I don't see a web browser being appealing as a platform, because there's no way for developers to advertise to users.
That's also only indie games. AAA games use their own launchers, because they don't _need_ the discoverability from being on Steam. So they don't, and avoid the fees. If anything users _want_ the Steam monopoly, because they like the platform, and hate the walled garden launchers from AAA companies.
(I work on high end rendering features for the Bevy game engine https://bevyengine.org, and have extensive experience with WebGPU)

What Are Const Generics and How Are They Used in Rust?
I was working through an example in the repo for the Bevy game engine recently and came across this code

WebAssembly Playground
That's possible. I did spend quite a bit of time tinkering with compiler flags, and followed the recommendations.
Some notes I found just now seems to agree with my results, though: https://github.com/bevyengine/bevy/issues/3978#issuecomment-...

Immediate Mode GUI Programming
I cannot recommend immediate mode GUI programming based on the limitations I've experienced working with egui.
egui does not support putting two widgets in the center of the screen: https://github.com/emilk/egui/issues/3211
It's really easy to get started with immediate mode, it's really easy to bust out some UI, but the second you start trying to involve dynamically resized context and responsive layouts -- abandon all hope. The fact it has to calculate everything in a single pass makes these things hard/impossible.
... that said, I'm still using it for https://ant.care/ (https://github.com/MeoMix/symbiants) because it's the best thing I've found. I'm crossing my fingers that Bevy's UI story (or Kayak https://github.com/StarArawn/kayak_ui) become significantly more fleshed out sooner rather than later. Bevy 0.13 should have lots more in this area though (https://github.com/bevyengine/bevy/discussions/9538)

ECS, Finally
I've also been enjoying building My First Game™ in Bevy using ECS. The community around Bevy really shines, but Flecs (https://github.com/SanderMertens/flecs) is arguably a more mature, open-source ECS implementation. You don't get to write in Rust, though, which makes it less cool in my book :)
I'm not very proud of the code I've written because I've found writing a game to be much more confusing than building websites + backends, but, as the author notes, it certainly feels more elegant than OOP or globals given the context.
I'm building for WASM and Bevy's parallelism isn't supported in that context (yet? https://github.com/bevyengine/bevy/issues/4078), so the performance wins are just so-so. Sharing a thread with UI rendering suuucks.
If anyone wants to browse some code or ask questions, feel free! https://github.com/MeoMix/symbiants

Intel CEO: 'The entire industry is motivated to eliminate the CUDA market'
These days, some game engines have done pretty well at making compute shaders easy to use (such as Bevy [1] -- disclaimer, I contribute to that engine). But telling the scientific/financial/etc. community that they need to run their code inside a game engine to get a decent experience is a hard sell. It's not a great situation compared to how easy it is on NVIDIA's stack.

I made a fast and ergonomic crate for trait queries. Now, you can easily query for `dyn Trait`!
For some good real-world use cases, check out this thread: https://github.com/bevyengine/rfcs/pull/39

Bevy 0.8
I'm the author of the draft Many Worlds RFC. Current plan is to get scheduling sorted out, then pick that work up again.
- Programming a Rogue-Like with Rust

Improving upon Entity Component Systems, introducing DG-ECM!
Yep, we do this, it works great! We stole it from hecs and Amethyst before us. There's a nice write-up of the theory in the scheduler rework the team has been working on for the past few months.

Bevy 0.7: data oriented game engine built in Rust
I can tell you right now that there’s an entire channel in the Bevy discord server dedicated to making an out of the box api for multiplayer. If you want the current state of it, check out this RFC. https://github.com/bevyengine/rfcs/pull/19 I’m really excited for it when it eventually comes out.
-
Bevy 0.7
I think making it easier for systems to observe the effects of Commands from other systems is a critical missing piece of the Bevy ECS puzzle. "Stageless" is a solid, holistic solution to the problem and we're seeing the community slowly establish consensus on that design. There is already a draft implementation in the works. And I think "stageless" is most likely the solution we will land on.

Announcing bevy-egui-kbgp - an improved keyboard and gamepad story for egui in Bevy
Cool! Looks like a nice complement to the RFC about keyboard navigation!
-
Bevy 0.6
This should be fairly feasible: although you'll probably want to wait on (or implement) the dynamic components RFC. The comments above are more to the effect of "writing Rust is easier and more convenient than you might expect".

Bevy’s First Birthday: a year of open source Rust game engine development
You will be happy to know that better/updated documentation is planned. It was briefly mentioned as "the new Bevy Book effort" in this paragraph of the blog post and there are a ton more details in this RFC. Your participation would be more than welcome!

Placating the borrow checker for systems that depend on a component plus the same component on another entity?
So, several of us have been working on a relations feature for Bevy: first-class support for those sort of "target another entity with a component" patterns that keep cropping up. There's a lot to be done, and it's at a point where it can be chunked out, so if you're interested in helping out come say hi on Discord :)
