Ratchet and Clank 3 contains all the humor and gadgetry of the past games right from the get-go. The only immediate change I have noticed in my hour and a half of play is the level up system for Ratchet's health and guns. This makes it even more fun to switch guns often and play through any extra things like the VR training. The difficulty is much higher right from the second level compared to the previous games. I guess the designers figure if you made it this far, it is time to up the ante. Additional cool things are 16x9 and Progressive scan support!
