Scripting language for python game

Why not Python itself?

From my experience, which may be somewhat limited, I think it's better to use classes and extend them. It allows for much more variation, but I suppose it would be harder for a beginner. If you have a class with attack(), update(), etc, that you can override, you can call those functions from the base class container in the engine. If you make it open source and have well written code, I think a lot of people would pick it up. I've come to hate scripting myself, because it seems messy and limited. Personally, though, for a platformer, I think a visual editor to make more levels would make more sense and then just have a way to add the enemies already created.

I will go for classes, a lot of different enemy types and a level editor

Thanks for your help :)

since python is an interpreted scripting language, adding an interpreted scripting language to the engine that isn't python seems sorta silly.

I use a component base system for my entities so I can define my units abilities in editor.
I also have a script component for writing new abilities with script.
