To me, Godot is the only game engine I would ever consider using. Unity is bad because you never know what shitty stuff they’ll do next. Unreal probably doesn’t work on Linux and unreal script sounds like a terrible idea. If I had to figure out all those extremely difficult math problems like angular velocities, quaternion math, rotation matrices and shit in an obscure programming language, I would stop to rethink my life choices. It’s already hard enough doing this in more widely used established languages even with decades of stackoverflow posts available.

Besides Godot, you can always make your own. Use a graphics library like orge or Irrlicht, a physics engine (reactphysics3d for example), something for sound like openAL and once you get them all glued together, you have a game engine.
