Pretty much whatever expensive snes game that you want, the sfc version is cheaper. I know they're going up in price lately, but still usually much less than snes.
As long as the game doesn't have too much text, you're good to play.
I've considered sfc for games like: final fight guy, mega man x2 and x3, castlevania Dracula x, demons crest (ultimately went for snes version on this because of the text in game menu)
