The Legend of Zelda: A Link to the Past
Super Metroid
Final Fantasy VI
Super Mario Kart
First 3 are a lock imo, although FF VI could be swapped with IV considering IV is the prototype. After that it's a wildfire. Super Mario Kart is basically the OG Mario spin-off which paved the way for every kart, sport, and party game that came after in the Mario franchise. Yoshi's Island is pretty much the first succesful Mario spin-off if I'm not mistaken. Street Fighter II is Street Fighter II, probably equivalent to GoldenEye on the N64. Star Fox is Mode 7 crazies.
How paralyzingly dull, boring and tedious!
