  1. …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…

  3. …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!…

  8. 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.
