Thanks for the input, guys. Damn that's a lot of stuff. =P
Definitely going to look into at least Megaman, Kirby Pinball, and Super Mario Land. I never had the patience to finish any of the old school Zelda, Megaman, Castlevania, or Metroid games on the NES, but maybe having them on a handheld in a train or something with nothing better to do will help.
Ultimately it'll probably come down to what I can get for cheap enough, though. =/
