This may be the Greatest Ratchet and Clank to Ever Come Out. This has more levels, more weapons, upgrades, stuff like that. Plus, you get two Robot Minions, that you can freely customize. This game has really good gameplay, and may be the best combat game for PS2. This game is amazing. The Weapons are awesome too, from Rockets to regular Dual Pistols, that may cost from 100 bolts to 1,000,000 bolts (if your wondering, bolts are money). Sadly, Clank has NO role in the game, hes more like a cheerleader, in a way, but can provide useful information. Another sad thing about this game: Real bad multiplayer. I mean, you have an awesome single player, but the Multiplayer is just Bad. You fight each other, which is not that much fun in this game, and may be BOR-RING! But This game, Otherwise, is amazing. And Cheap too. So if you have a Playstation 2, then this may be a game for you.
