The first Ratchet and Clank game for the PSP is actualy a good one.

User Rating: 7.5 | Ratchet & Clank: Size Matters PSP
The first Ratchet and Clank game for the PSP is better than I thought it would be. There is a large variety of weopons that you can level up to become more powerful and you can even buy add ons for your guns to help you in tricky sitiations. The graphics are good and the controls work smoothly on the PSP, and there is a lot of mini games you can play to earn extra armor and cash. The story is good with mini games you just play for that extra peice of armor you need to complete your collection. The story seems to role on by quickly, but then you have the option to replay the story over again with all your fully upgraded weopons and powerful armor. If you complete a set of armor it unlocks a special effect that helps you in combat situations. The campaign is action packed and the checkpoints are well placed so the game isn't to easy but not too hard. You can do other fun things apart from the campaign like like Ratchet goes skyboard racing and Clank enters a destruction derby with a lot of weird vehicles with weopons attached. At the end of it, I really liked Ratchet and Clank Size Matters, and I hope they make more Ratchet and Clank games for the PSP.
