1 Super Mario Galaxy
Formerly known as Super Mario 128, the release of Super Mario Galaxy solidified the Nintendo Wii as a console that any kind of gamer couldn't go without. Mario's long-awaited return to 3D platforming was made all the more amazing by inventive gameplay and unforgettable levels that said 'so long' to the laws of gravity and physics. With Super Mario Galaxy, Nintendo also proved, once again, that the plucky plumber's still got plenty of tricks to show off, and he's just getting better with age. On top of everything else Galaxy has going for it, it's easily one of the best looking (and shiniest) games on the Nintendo Wii yet, with graphics comparable to those seen on its next-generation console competitors. Welcome back to the world, Mario. We missed you.
