Rock Band seems to have more to offer right now, but it's price tag is a little too high for me so I'll be picking up Guitar Hero 3 instead. But if you can afford it, I say get Rock Band (you could always just get the drums and the game and pass on the other instruments if that's what your most interested in). Of course neither game has released complete song lists and that, as I'm sure you know, is a big part of these games and could affect your choice.

Resistence 2

hands down jak 4sphinx-shadow

Absolutely! The Jak and Daxter franchiseon the PS2was one of my favorites, and I would love to see it continue on to the PS3.

Could be interesting. If it's like Pokemon Snap I might just have to pick it up. I really enjoyed that game. Of course I was a lot younger then, so I'll have to see how the reviews go.
