Not a game dev but I’ve had interest in using Unity for machine learning. I’m now trying out Godot since it does have quite a few ML libraries and it seems to be maintained better than Unity’s ml-agents.

Unity-ml-agents is quite a hassle to deal with but a few months ago I wasn’t able to find any altrrnatives. At least one good thing that came out of this is that I learned that there is an alternative to using Unity now.
