Through pure nostalgia, and the fact that they are some of my favorite games of all time:
-Secret of Mana -Super Mario RPG: Legend of the Seven Stars -Legend of Zelda: A Link to the Past (Which I believe to be the best Zelda game)
Now, I did not download Ocarina, Majora's Mask, Legend of Zelda, or Zelda II. Because I already own the Gamecube collection as well as the master quest (and now I have them for my 3DS [Besides Majora's Mask]).
I definitely downloaded that game as soon as I saw it on the VC. I have fond memories of playing that game in Blockbuster back when video stores used to have demo systems with full games in them set up existed.
It really is a shame they never created a sequel, Though a little understated and lacking in content is was certainly a great concept.
just imagine it for the Wiiu, sitting in a office chair spinning around and gazing and your favourite pokemon through the Wiiu's touchscreen. they could have a different island for each pokemon generation
I'm a huge fan of Super Metroid. I owned a N64 and an NES growing up but I completely missed out on the SNES. Thanks to the Virtual Console I've gotten to experience some great games. So far I'd probably rank them Super Metroid> Mega Man X > Super Mario World.
Without a doubt Sonic & Knuckles and Zelda II: the Adventure of Link. Sonic & Knuckles for the sheer amount of content you can have if you have all the other Sonic games and Zelda II for underrated classic 2D Gameplay :)
