So if you've never played a Ratchet & Clank game, do, but don't make it this one. It's still better than a lot of the rubbish out there but it's nowhere near as good as the other games in the series, and you can pick those up second-hand for less than a fiver each. Then there's the superb PS3 game, of course. Even fans of the series will be disappointed by Size Matters. If you're a real completist, try the PSP version. Alternatively, just play the old ones again. Speaking of which, must get on.
