I still consider Game Maker to have the best standard library for actually making 2D games of any engine I've encountered.

It is really quite good at what it does, and it's an easy way of building quick and dirty .exes too.

I do wish knowing GML was good for something somewhere else though. Or that it used another language like Python for its scripting.

Nothing would make me happier than being able to use Python with Game Maker's functionality.
