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.
