The newest chapter of the Paper Mario story isn't just out of this world ... it's out of this dimension. What at first glance appears to be a 2-D sidescroller ripped straight from the pages of the Paper Mario universe soon turns into a 3-D action-adventure that defies all video game logic. Fusing 2-D and 3-D perspectives, not to mention RPG and platformer elements, the game slips back and forth between dimensions. The action sprawls across eight worlds filled with traps, puzzles, bizarre mysteries and items that often draw themselves out of thin air. Oh, and just because Mario's in the title doesn't mean he's the only star. Players also get to play as Peach and Bowser.
