Godot, Unity, Stride, Flax and even jank niche engines like NeoAxis generally have pretty good C# integration! If you look more at Stride, you’ll see that even their physics engine is C# which is insane in the best possible way: https://doc.stride3d.net/4.3/en/Manual/physics/index.html and https://github.com/bepu/bepuphysics2 Very cool language and as much of a mainstay in gamedev like something like Lua. It surprises me that Java never got similarly big despite their GC improvements, though jMonkeyEngine was a nice project last I looked.

My favourite is probably Bepuphysics due to its C# nature: https://www.youtube.com/watch?v=tjtwSq3u6Dg Unfortunately it was created before Unity could use vectorization and other C# engines were just starting out as well. The source, a great resource for learning C# SIMD, even though its a few years old by now: https://github.com/bepu/bepuphysics2

> That's not to say that you couldn't write a commercial game engine with something like C# that stands shoulder-to-shoulder with unity and unreal, but it doesn't seem like anyone has attempted to do so. Stride should mostly fit the bill: https://github.com/stride3d/stride Their homepage: https://www.stride3d.net/ Even the physics engine they use is in C#: https://github.com/bepu/bepuphysics2 Not a very popular game engine (never got the attention that the likes of Godot did), but it's nice to work with! It’s up there with Stride in regards to the “indie” game engines I like, maybe alongside jMonkeyEngine (since you typically don’t see that many Java game engines either).
