From what I've heard, it's great. This is a definite pick-up from me.
I actually think I'm going to pick up Punch-Out!! tomorrow and hold off on Boom Blox. I'm suddenly very interested in Punch-Out!!.
I also want to do that, but unfortunately money is tight at the moment. Maybe when I get my next paycheck in two weeks... Then again, I need money for The Conduit and upcoming sports games.
I NEED TO WIN THE LOTTERY.
Don't rush into buying a PS3 right away, rumor is Sony is announcing a price drop at E3. So I'd wait.
