GTA meets Looney Toons
The story may not be Shakespeare, but they do quote him. The super powers are a nice twist, and I agree with the Gamespot review, I haven't really driven a car since I got superspint and jump.
The only con I have about the game is the random visual glitches that the "simulation" has and it can be distracting when the wall of a building looks like the bricks are water flowing down the side. I know they added it to the game to give the sense of not being in the real world of Steelport, but it does get a little distracting
