The only thing this has that I don't already own and care about is Secret of Mana (Earthbound I don't give a shit about, always felt it was overrated over stuff like the Mana games, and a lot of other SNES/SFC RPG's, Chrono Trigger I have on the PS1), it has a few games I don't own on it, never had the desire to own them (including both Star Fox games and Super Punch Out). They'll do what they did with the NES Classic, make so many, let the consumers kill each other trying to procure one, then spend a shitload of money on Ebay to have one. No thanks.
Edit: Looks like the Japanese one has Fire Emblem and Panel de Pon (big FU to Tetris Attack, now that I know better, I hate changes to games to appease to certain markets, especially now that I know better). More people know about Panel de Pon now than they did back in the 90's, not to mention the Japanese version actually gives you a hidden extra fight if you do well in the game (that versions "Bowser" is actually the second to last guy, and not the final like in TA. And I know he isn't Bowser, just using him as an example). Especially puzzle games, they did it for Magica Drop (all characters personalities, gone), Puyo Puyo (Kirby and Robotnik, grrrr), and Puchi Carat (no pre match dialogue, half the endings cut out), and Panel de Pon (which I don't have.....yet. That's why I go Japanese versions for my puzzle games. You just don't screw with my puzzle games.
