Zelda OoT on the DS would probably turn out like Mario 64 DS, enjoyable but would kill your finger and frustrate you, not unless Nintendo releases some kind of thumb stick to attach onto the D-pad.I second Zelda Ocarina of Time remake and Theme Hospital (even better: a mashup between the two. It has to be perfection!).
And I add: a Mugen kind of port to NDS that looks like Jump Ultimate Stars and uses both screens as battlefield that let's designers/programmers create their own characters that you can download and install and then there is a web community where users rate characters and discuss about them and you gotta catch 'em all...muhaha! You know, MUGEN.
P.S: I still can hear that voice in my head from when I used to play Theme Hospital Dr. required in inflator room.
Oh! and I love Street Fighter and all it's characters, specially Street Fighter Alpha 3, but the NDS is just not the right platform for games like that because of the controls and because only chiby characters look good on it's tiny screens (IMHO).
