Which Ratchet & Clank PS2 game is the best?

Ratchet: Deadlocked is the best one on the PS2, but Ratchet and Clank: Up Your Arsenal comes in a very close second.

Also, the ones for the PS3 are great to play too.

As a last note, there is another one that isn't too well know that you didn't mention. It is called "Ratchet and Clank: Size Matters". Yes, it is for the PS2 also. I haven't played it yet.

The camera is a LITTLE steadier in Jak 3 for most of the scenes. When you are in the desert, however, the camera has to move around quite a bit as you race around. If the earlier R&C games made you dizzy, then Jak 3 will to eventually. As for the story line, Jak is a lot more 'mature' than R&C especially the third game, which is the end of the normal series (for now).

I really loved Deadlocked, but its probably the least well known ratchet game, but Up your Arsenal was also really really fun as well.

that is actually a really hard question. it isnt deadlocked, that games was WAY to trigger happy. other than that it could be any of them, probably going commando

Up your arsenal hands down
