I must agree: I don't get it.
You say every platform has a preferred language which should be used instead of others because they would be "limiting", and that Python is a categorically bad idea.
But the original poster didn't indicate which platform he was choosing. What if his platform of choice is Pygame? What if it was the .NET CLR (which effectively "comes with" languages like Boo or IronPython)? Wouldn't Python then be the ideal choice?
And before you dismiss Pygame as too limiting to be a platform, note that one of the games in the article is flOw, originally written for the even-more-limited Flash platform.
