Ratchet & Clank is a fun game, but once completed doesnt really make you want to go back for more. Still good, not great
Good point about this is the graphics are superb, and the enemies are inventive, as well as the weapons. The humour is okay, if you like cartoon ones that is.
The bad ponts are that the gameplay isn't long. As soon as you get it, you feel like throwing it in the bin, as there aren't any multiplayer options.
Overall, Ratchet & Clank is an entertaining game, that anyone who has liked Crash Bandicoot: The Wrath of Cortex might want to give a go.
