Enterbrain created another Game Maker recently that is tailored to Action Games. Unsurprisingly, it's named Action Game Maker.
Game Maker can create some interesting feats, only if you know how to code in its language. I guess you can say the same for RPG Maker XP, but yeah, Ruby is a great language. ;x
I don't know what else to say. Welcome (back?).

EDIT: By the way, there's a rule on Double Posting. No big warnings or whatever though.

You can make a double post as long as 24 hours have passed. ^^
