1: Super Mario World (Best 2D platformer ever)
2: ISS Deluxe (Fantastic football game)
3: Castlevania IV (The music alone is worth the money back in the day)
4: Turtles IV: Turtles in Time (Best arcade game played on SNES and one of the best conversions)
5: Super Ghouls N Ghosts (Music, and fantastic gameplay and obscure levels)
Other memorable games : Secret of Mana, pocky & Rocky, U.N Squadron, Axelay, Darius Gaiden, Mickeys Magical Quest, NHL series ( the only EA franchise you can respect

SNES is the best system ever made. J-RPGS in their prime along with Platformers, and tons of other great titles
