This could have easily been made to PS2.
Ratchet & Clank: Tools of Destruction doesn't really give anything new to the franchise. Maybe a few new weapons, which all kinda suck, except the Tornado Laucher, but controlling it with the SIXAXIS is like steering a car with your feet. The levels are hardly any bigger than in the previous games (don't know if its good or bad) and the graphics are hardly improved. Sure there is some more detail, but there is really nothing that couldnt have been done with the PS2 (exept the HD res). It seems that Insomniac was desperate to get this game out as soon as possible to give PS3 its dose of platformers that they ignored all that could have been done with the PS3:s engine and the capacity of blueray disc.
I was deeply disappointed with this game. It was short, without much to extras. The guns were pretty much just ported from the previous games and the level design was poor compared to previous ones. I still hold Ratchet & Clank 1 as the best in the series.
