I am not convinced that that matters. Great games have been made with Godot (Cruelty Squad) and GameMaker (Sexy Hiking), or with no engine at all (Minecraft, Cave Story).

Great games have been made with probably any tool you can think of. That doesn't mean the tool is good, or that you should choose to start making a serious game with it.

I do not agree with your unsupported claim. For example, I would bet no good games have been programmed in Haskell. As far as I am aware, no great games have been made with the Unity or Unreal engines.

Oh, I thought we were having a genuine discussion. My bad.
