It's interesting that now that the NES Classic and SNES classic are in stock, Gamestop have been getting them in used.
I got one of each, the NES is fun, mainly picked it up for Legend of Zelda. I wasn't too much of the SNES gamer but Super Mario RPG, Link to the Past, Super Metroid, Secret of Mana and even FFIII makes it a worth while pick up.Atleast the SNES classic still comes with two controllers.
Quite frankly I only got the snes retro for the controllers, I couldn't give a ***about the "hardware" also an interestingly note, aside from the shell it's the same hardware with just a different kernel. You'd be better off with a Raspberry Pi and one of those wireless BT controlelrs for snes.
SNES is one of the best systems ever made, and I've probably beaten ALTTP 100% probably about 100 times.
