With the series turning 25 this year, one might figure that a game with the words Super Mario would offer nothing new to jaded longtime fans. Yet Super Mario Galaxy 2 does exactly that — and in spades. Nintendo's plumber with aplomb bounces through an interplanetary adventure so brimming with ideas that it makes your head spin. The game's Cosmic Guide makes sure players of all stripes can finish this very challenging adventure. It all happens in bright, inviting worlds that prove that family-friendly doesn't have to mean deadly dull. SMG2 shows that Mario's got plenty of jump left in those little digital legs of his.
