I've been looking at GameMaker, just gathering dust on my computer as Hammer Editor is starting to be used less, and I'm thinking, "I need a swan song". (Might help if I have a series to HAVE a swan song with), but yeah.

Its gathering dust and I have an idea. Should I create a game? One thing to test if I can still do it? I've gathered good skills with Hammer Editor, and I think I can shoot that skill over to Game Maker.

So here's the deal. Should I try, and should it be a speedbased Platformer or an RTS?
