Bought it this morning, just played it for an hour :)
It's such an amazing game all around, still love playing it even though I beat it like 50 times on the gamecube. All the new touches are great, I like the new background on the PDA. All the minigames are great, now I can finally play All You Can Eat without being at Comic Con. I tried to play it online, but everytime I tried, it would say everyone left, dunno if that's technical or if a lot of people just decided to quit. Missile Mastar is awesome as well, although, no music?
I'll play a LOT more later, but I'm definately gonna force everyone I know with a 360 to buy it. GREAT job guys, it's amazing! And definately looking forward to Castle Crashers!
