Summary: I'm a big fan of the Ratchet and Clank games, as well as the Jak and Daxter games. This one is very good, I would have to say it is the best game on the PSP, maybe joint best with Grand Theft Auto: Liberty City Stories. I wasn't too impressed with the similar game Jak: the Lost Frontier, this one is much more fun, it's really great, the controls, gameplay, level design and it's not too difficult. Definite 5/5 from me for this psp game.
Summary: I had never played the Ratchet and Clank series before buying this version . It turned me into a fan loved the psp version so much I bought the ps3 version and looking forward to more Ratchet and Clank . This psp version is amazing psp at its best . The psp still ahs much to offer compared to Vita , sorry Vita but you dont have Ratchet and Clank yet . A must for psp owners .
