I have played and loved every Ratchet and Clank game, actually, Deadlocked was kind of a disappointment. I have also played every Jak and Daxter game and loved them just as much as I did Ratchet and Clank, and I love Ratchet and Clank games. About Sly Cooper, I have, again, played every one of those and liked them a lot. The first two were amazing, and the third one was kinda weird, very fun, but the ending seemed to have come out of nowhere and the voices seemed completely different. So, in conclusion, I would pick up every Jak and Daxter, every Ratchet and Clank, and every Sly Cooper, they are all the best platforming games on the PS2.
