What about those third party games like Bubsy the Bobcat and Joe & Mac? Odd puzzle games like Yoshis Cookie.
Wait, this is SNES. I was thinking of Battletoads and Double Dragon for NES. Are they the same game still? NES games were the hardest of all time.
Full list of games I remember (no order): Super Mario World, Super Mario All Stars, Bubsy The Bobcat, Super Castlevania IV, Legend of Zelda : Link To The Past, Mortal Kombat, Killer Instinct, Zombies Ate My Neighbors, Wheel of Fortune Deluxe, Ms. Pacman, Paperboy 2, Home Alone 2, Super Ghouls N Ghosts, there's more I will edit this later.
SNES will have to be my favorite console ever. I has a NES but I was too young and sucked at games too much to actually appreciate. My favorite games that immediately come to mind are: Chrono Trigger Rock and Roll Racing TMNT - Turtles in Time Super Mario World
