Bomberman 64 and Bomberman 64: The Second Attack. For the 3DS.
These were fun little games for what they were, and with modern improvements and some updates, some minor (Make the bosses not pants-on-head retarded and speed them up so they can actually be challenging) and some major (Graphic overhaul, wireless multiplayer, put both games on one cartridge), they can give me one of the few nostalgia trips I've never had. Some things better stay the same, though *coughSoundtrackcough*
Banjo Kazooie and Banjo Tooie. For the 3DS.
Once again, a graphics update and put them on the same cartridge, and you've got a best seller for the 3DS!
