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.

Helion: A modern fast paced Doom FPS engine in C#
Go and have a look at Bepu Physics v2: https://github.com/bepu/bepuphysics2
It can be quite performant these days, sadly I'm stuck developing in Unity Mono C# which is quite a bit behind.

SIMD Matters: Graph Coloring
> The other problem with simd is that in modern cpu-centric languages it often requires a rewrite for every vector width.
It does not: https://github.com/bepu/bepuphysics2/blob/master/BepuUtiliti...
Also you can’t go to GPU for most tasks SIMD is used in CPUs today. Good luck parsing HTTP headers with that.

Quartz: A Deterministic Time Testing Library for Go
This may be your personal experience but it is used successfully and happily by many in a variety of domains way different to "boring OOP back-ends". No popular general purpose language is confined to a single domain like you describe. C# lets you do things like writing a competitive Redis implementation[0], advanced physics engine that beats Jolt[1] or a game engine that does not rely on C++ or C[2], cross-platform applications[3] and so on and so forth. The language itself lets you go from high level FP style approach for business domain modeling to very low-level data crunching that is competitive with systems programming languages.

Current state of 2D game code-first frameworks?
The best pure-C# physics library (hands-down) is bepuphysics2, which unfortunately is mainly a 3D physics library, but could be used for 2D if you wanted to get your hands dirty.

Open Source C++ Physics Libraries for Dedicated FPS Server?
Bepu Physics is pretty good and is written in really optimized C#, the author's blog post are really interesting to read.

Early Demo of Dynamic Blocky Lighting System
I use https://github.com/bepu/bepuphysics2. I haven't worked with 3d physics engines before so I can't really comment on it's quality but it is definitely an impressive project! The developer is very active and helpful and some of the demo scenes are pretty large and complex.

- Since you're asking yes u can use C# in unreal

Unity plan pricing and packaging updates
https://github.com/nxrighthere/UnrealCLR
I'm also surprised though they haven't just gone and added C# support as a first class option, it seems like such an obvious win.
-
Those who have worked in both unreal and unity, what have your experiences been like?
You can use C# in unreal: https://github.com/nxrighthere/UnrealCLR, they even got an epic megagrant.

C#
Surprise motherfucker

Will unreal add C# as an extra language?
UnrealCLR

How come Godot is by far the most recommended game engine, yet there are very few noticeable successful games made by it?
UnrealCLR has an Epic megagrant and supports .NET 6 already.

I’ll take “sentences I never thought I’d write” for 200, Alex
I mean, technically Unreal does have C# support via their community, but it lags a bit behind the engine and isn’t as fully featured as Unity or even Godot https://github.com/nxrighthere/UnrealCLR

Why is unity partnering with a company best known for making malware?
Biggest thing to note is that there's no stable release as of yet, so using UnrealCLR right now might not be the best idea for commercial games. There's also a few engine APIs missing from UnrealCLR, but from my own understanding, most of the common ones are there and ready to use.

Unity Employees "Mad and Stressed Out" Amidst Unexpected Layoffs
Wish they would turn this into an officially supported project: https://github.com/nxrighthere/UnrealCLR
What are some alternatives?
When comparing BEPUphysics and UnrealCLR you can also consider the following projects:
JoltPhysics - A multi core friendly rigid body physics and collision detection library. Written in C++. Suitable for games and VR applications. Used by Horizon Forbidden West.
Duality - a 2D Game Development Framework
Stride Game Engine - Stride (formerly Xenko), a free and open-source cross-platform C# game engine.
osu-framework - A game framework written with osu! in mind.
MonoGame - One framework for creating powerful cross-platform games.
