My first instinct is to say, "Of course you should!" because I think everyone should play the SNES. :)

My second instinct is to say, "Yes, but...", because we're going back more than twenty years at this point, and games are different. I, personally, love the 16-bit look on games, and there are some bona fide classics from this age, not least of which are the holy Nintendo trinity of Super Mario World, Super Metroid, and Legend of Zelda: A Link to the Past.

Secret of Mana is one action RPG that I think everyone should experience, so I will say yes: grab yourself an emulator and get to playing. :)
