Buy this! A bit of full-on bias for you there. Ratchet & Clank are back in excellent form since the co-op orientated All 4 One and the craptacular Q-Force. It's so cheap already because it's shorter than usual, but the length of the game (about 6 hours first time round) is terrific value for money at this price. I've finished it three times already for a nice new Platinum trophy. One of the best action platformers I've played in years.
