Forget about the first Viva Pinata, just get the second one. It's pretty much the same game with more stuff. Bayonetta is a good pick too. And yes, Crackdown. It's better if you have a friend to play with. I once played co-op for about 10-12 hours straight. But you can have fun with it alone too. Oh and you can't install Crackdown to hard drive. I don't know why this is, but it sucks.
