GameHelper have got a review of the new Ratchet and Clank : Size Matters game on the PSP.

Size Matters is that rare example of a title that succeeds in upping the ante when it comes to what gamers can, and should, expect out of their portable system.

Its a nicely written review that makes me want to get my hands on this game, which is always good news for the PSP as ‘must have’ games is a little thin on the ground in comparison to other systems on the market.

There is even a youtube video of the game in action, so you can see what to expect :

Pop over to GameHelper and read the review, then go out and buy the game.
