Well, there are no 1st party Nintendo games but there is a port of Megaman 2 that is actually very good. (But you MUST go into options and turn in landscape and classic mode on, otherwise it sucks) Other games you may like are Rayman 2, Simpson's Arcade if you like beat em ups, the Zenonia games which are similar to Zelda but have their own flair, Assassian's Creed 2 which is a decent port of the DS one, and Castle of Magic, which is almost a big mish-mash of classic games. Also, Dark Void Zero is comming out soon which is an 8bit sidescroller in the vein of Megaman and Metroidvania which seems cool. Just dig a little deep, and you'll find great things
