For a game that was ported and doesn't have the best graphics, this game really beats out some of the other 360 games available. I picked up (as a result of buy 1, get 2 free) Bully: SE, Mercs 2 and Splitnercell Double Agent... Bully > both. Bully is also better than most of the other games in my collection as well.
It's quite addicting, the unlockables are bountiful, little details in your room are cool, and there's so many things to do. If they made a Bully 2, I'd probably buy it retail for $80 (after taxes and all)
Nobody cares that you played GTA 4 for a few hours and stopped because it was boring. Seriously. You're not original.
