The only remake I truly desire is a 3D ALTTP, (I have wanted that ever since OOT) but it has to be as if all they did was take the camera from above and put it behind link.
I wouldn't mind portable versions of OOT and MM, just because they are the kind of games that I would LOVE to have on trips.
and Motion sensitive versions of OOT and MM would be cool, but I could live without them.
Anything else is unnecessary.
the only thing they could possibly do to make ocarina of time better is to fix the combat system so it's more fluid like in windwaker or twilight princess. I'd much rather they remade the first two games like they were gonna do with the oracle series or rerelease majora's mask with all the annoying glitches from the collector's edition fixed.
