The GC controls for TP aren't really that new, how are they kicking your but?

But Yeah, 2 games for less then one is probably the safest bet, as I love God of War, but can't vouch for Collosus.

However TP is funner than God of War. The enviroments are amazing, and overall While the Gameplay isn't exactly new on the GC, some of the new Gadgets, noteable that spinny top thing, are fun as hell.

Though KH 2 is fun, I'd say go for TP or GoW and Colossus.
