"Featuring a pair of wacky robots in a quest to save the universe, Ratchet and Clank may offer the same old basic platform scenario--run around, elude or destroy enemies, jump, and negotiate treacherously dynamic environments--but it has a number of things going for it that place it among the best titles ever in this genre."

I played Ratchet and Clank: Going Commando before trying the first one. While that one has a lot more weapons, the first one is just as much fun. A really terrific game, and I'll play it repeatedly.
