It's been a while since we've seen Mario in his 2-D form since his debut in to the 3-D realm. Nintendo brought back that classic design with New Super Mario Bros. on the Nintendo DS, and it let us all know that Nintendo can still make a great 2-D Mario platformer. Following up on that success, New Super Mario Bros. moves to the Wii and this time adding in some multiplayer gameplay to switch things up a bit. Whether you're playing by yourself or others, this is classic Mario gameplay and it's still lots of fun.
