I mean, don't get me wrong, this isn't the next A Crack in Time, but it is a lot of fun, and fairly inventive. I haven't tried playing online yet, but the single-player campaign has been fun, and gives you a lot more content and replay value than Quest for Booty.
So far, I'm enjoying it a lot more than All 4 One. Only thing that's really disappointed me so far is that apparently my TV's resolution isn't good enough to play the game in 2P split screen. A shame, as I'd been playing through the campaign in Ratchet Deadlocked with a friend, and we were hoping to try this one out in co-op.
