This game definitely deserves a full 5 stars! I have also loved Ratchet and Clank from the start, and believe me, you will not feel let down by this wonderful title! For this low price, you definitely get your money's worth, no doubt about it. My best personal 'up' of this game is the amazing graphics, you will drool! For a Ratchet and Clank game, the lens flares and graphics is TOP notch. I also loved how you have to use your Gold Bolts to purchase ultimate versions of your weapons (after completing the game), this is the same as the first game so i'd say they went back to their roots! Clank also has mini levels to complete, side scrolling style, where you can manipulate the gravity of the level any way you choose! Totally wow!
The only thing to take into consideration is that this game is NOT on the long side of things, it's in fact pretty short, but depending on your play style, going back to level up weapons is always fun! Once again, for such a cheap price, it is AWESOME!!! :D
