Yoshiaki Koizumi, director for Super Mario 3D Land, recently expressed a desire to possibly remake past Mario/Zelda games for 3DS.
When quizzed by Official Nintendo Magazine on going back and improving past games like the Zelda team did with Ocarina of Time 3D, Koizumi mentions how he would like to use the improvements in technology to someday revisit past games.
One of the examples given was the use of the Iron Boots in the original Legend of Zelda: Ocarina of Time for the Nintendo 64. Koizumi-san worked on the interface for the game, but didn't realise that there would be a temple that relied so heavily on switching to and from the Iron Boots - the Water Temple. It's something like this that was addressed as a shortcoming with the original and improved on in the 3DS remake.
As for any specifics, Koizumi denied any interest in any one game that could be remade, but did mention Super Mario Galaxy and Super Mario Sunshine as two games that he would be like to see visualised in 3D, but not necessarily remade for the 3DS.
Guess I can't really say one title specifically because then the world will expect us to make it and I'll get into a whole lot of trouble!I can say that I really would like to see a lot of those games that use 3D worlds on 2D display just so I could see what they look like in 3D and see what kind of different experiences people would have playing through them on a 3D display. So in that sense I would love to see Sunshine and both Galaxy games presented in 3D, and a lot of the Zelda [games] would be interesting too.
Would you like to see remakes of other classic Nintendo games reborn on the 3DS or Wii U?
