This is my problem with Nintendo; apart from Megaman Legends 3 and the MGS3 remake (which will be new to me because I haven't actually beaten any MGS game to date) I have no reason to buy a 3DS.
Ocarina of Time? I have the Master Quest for the Gamecube. Why the fuck should I spend money on this game yet again? Many other people STILL have it for the N64. Fuck, even Wiiware has it for cheap, so you can't even claim that nobody has had legitimate access to it on a new/current-gen console.
I seriously doubt a game whose appeal came largely from the amazing atmosphere is going to play any better on a bus or in an airport terminal, 3D or not.
I have no problem with using old franchises in new ways (despite all the hate, I really enjoyed Phantom Hourglass because what it did with the controls and corresponding design space.) but this constant rehashing of the same exact old content is really starting to piss me off.
With Sony is refusing to put any fucking effort into fixing the PSP's control scheme and current generation consoles (PS3/360) deliberately stifling their game's design space to make an endless parade of God of War Devil May Cry clones/Generic Bling-Shooters, the 3DS might be the last place where its hardware limitations fall into that magic category that made the PS2/Gamecube/Xbox era so damn good and varied.
You have processing power, but not enough to release a game that sells solely because of how much bloom lighting and hi-res texturing. You still have to put some thought and effort into the game beyond "What guns are we going to give the players this time?"
Then again, the 3DS could just as easily fall prey to shallow gimmick-marketing like the Wii did.
