Yes, maybe it's a stupid thing to say. My thought was that the simplicity of the API takes out a lot of the complexity of it compared to engines with complex structures, entity hierarchies, event systems and features that need to fit a wide range of genres. Especially if you want to make something simple or just a prototype.

Probably better to say "Writing games is simple again" or something then. Though engines like unity or unreal would make 3d games a lot simpler to make than this, so it's only some kinds of games

You're right. I fixed it ;)
