Crash Bash deserves more than a 6.0!
The graphics are great and the sound is too. But it might get you angry because the game gets too hard and you might play something else. My favorite games are the polar bears and pogo. You can't go wrong with that.
Boss fights are still the same mini games but targeting one guy only. So overall Crash Bash is a great game and is a very good reason to get a multitap.
