Even in the niche realm of the role-playing game, Mario & Luigi: Superstar Saga is pretty out-there. Such Dadaist nonsense is all the more bizarre for being entirely typical of Nintendo, a company who appear to aim for new levels of unabashed quirkiness with every passing year. To their credit, however, this philosophy has really paid dividends here, in the first new Mario adventure for the Game Boy Advance. It's aesthetically fresh, filled with original creations, and presents a wholly unique mix of gameplay styles.
