Super Mario Galaxy wasn't just the latest and greatest 3D Mario game when it released in 2007 -- it redefined the platforming genre. Again. Nintendo's best designers rebounded from the excellent but still somewhat underwhelming Super Mario Sunshine on the GameCube and unleashed Galaxy, a meaty, deep adventure that married Mario's traditional fireballs and Koopaling knockouts with a healthy dose of M.C. Escher. Its game design is as smart and challenging as it is refreshing, and, Wii Sports be damned, it was and is worth owning a Wii for all on its own.
