Sometimes, it's difficult to remember that Mario got his start as a 2-D platforming hero. In recent years, his platforming adventures have mostly been 3-D, and he's been everything from a fighting game character to an RPG hero to a kart driver. To most of us, the image of Mario is still the adorable 8-bit hero who jumps on Goombas, grabs mushrooms and saves princesses from giant turtles. New Super Mario Bros. on the Nintendo DS gave us a taste of old-school Mario action, and it became one of the best-selling games on the system, placing on the top sales charts for months after its release. A handheld release just doesn't hold the same allure as a console game, though, and while New Super Mario Bros. was fun, it left us wanting more.
