While Unity is used a lot, it isn't as much as us managed languages fans would like, and the engine most folks are running for instead is Godot, written in C++, where GDScript is really taking getting used, instead of C# or non C++ extensions.

As big C# fan it saddens me, but things are as they are.

As you can see even by famous 2024 releases, multithreanding bugs or UB, aren't something most studios care about, there is always the next DLC.

And this an industry that was used to burn what used to be the golden copy of the game, before moving to the next game, there were no patches or upgrades.
