I still think programming is going a bit far.  I'll admit that there's more of a response to it than I had expected, but I think at present, it's probably a bit difficult.

Though I've thought about Game Maker and it's probably a little tricky too, mainly how it sticks everything into one large file (wee'd have to share it around which would be a pain).  Anyone know of a system which allows multiple files instead?

From what I've seen, a shooter and an RPG seem to be the most popular genres.  What about both? :P
