So you are going to be either button mashing? (Which is a terrible combat system.) Or you are going to be performing only counter-attacks? (Which isn't always the best kind of system.) I might rent it first or wait till it drops to $30 before picking it up(did the same with AC1). Though it seems that everyone is either "I hate it, it's just as bad as the first one!" or "It's awesome you should totally get it."
