The idea here is really cute - this is clearly made for kids to play with multiple friends/siblings as each one is given avenues on whether to work together as a team unit, or to vie for success as the sole winner (conceptualized smartly during the good-versus-evil loading screen tips). It's rare that you see this sort of freedom to choose between competition or cooperation in a game like this. That being said... FUCK. This is easily one of the most punishingly boring 100%s I've ever gone for - levels padded out with an excess of combat spam and pointless replay requirements. Even if you were just playing this casually, it's still got some of the most broken and mind-numbing fighting since Borderlands - 99 times out of 100 you'll be one-shotted from a full health bar with no indication that you'd even been hit. Some of the worlds are pretty, some are murky in the way that PS3 games can be murky. I'd rather play Skylanders and that's saying something.
