There are a LOT of games on the SNES that are worth owning... most of them are hard to find classics, and majorly role playing games.
*Super Mario RPG
*Secret of Mana
*Final Fantasy 3, though 2 is great too. 3 had a MUCH bigger world to it.
*Chrono Trigger. One of the first SNES games with over 10 separate endings.
*I like Shadowrun, and I never played the Genesis version... game still 0wns.
*Soul Blazer
*Donkey Kong Country 1. 2 and 3 were just rehashed, but 1 is still the best.
*Killer Instinct - Best Fighting Game ever made.
