From the VC: Bonk 3: Bonk’s Big Adventure, Donkey Kong Jr. Math, Landstalker: The Treasures of King Nole and Adventure Island.
From XBLA: Cyberball 2072 and Fatal Fury Special.
Best bets this week are probably Cyberball and Landstalker, but Adventure Island was kind of fun back in the day if a little surreal (then again, what platformer on the NES wasn’t?) and I’m sure some people will be all over Fatal Fury.
