Final Fantasy 6
Final Fantasy 7
Chrono Trigger

I'd love to see a FFVI remake.

I'm very unsure on a FFVII remake, I actually wonder what the game would be like without prerendered backgrounds. I don't like the idea of it oddly.

I'd like to see Ocarina of Time and Majora's mask updated and released as Wiiware. Wii controls plus a slight graphical bump up is all I ask for ;)

Some old Atari computer game Ithink named Eco. You started as a bug...had to eat and mate...and each time you comleted that you unlocked a genetic code then you could change what kind of creature you were. It took place in a park and you had to avoid predators.

-Xenogears (that game kicked ass on PS)
-Megaman Legends (With Wii controls and more detailed modes/textures will be awesome)
-ShadowGate (Pleaaaaaaseee!!!!)
-Top Gear Rally (this game rocked on N64)
-Secret of Mana
-The original Legend of Zelda
-Metal Gear 1 and 2 (not the Solid series)
-Snatcher
-Jet Force Gemini
-The original Turok: Dinosaur Hunter (Still my No1 Turok Game, I play it over and over again)
-Jedi Knight: DFII (with Wii Controls :))
........

The list goes on...

I would kill for
XWing,
Tie Fighter (please no console friendly "simplifications"),
Ultima7a,
Ultima Underworld1 (best game ever),
Original C&C (just great graphics and better AI no bigger armies)
...

Metroid Prime series: They were great games, but they really should have been third person experiences.

Chrono Trigger: I want to see the Kingdom of Zeal fall in HD.

Metal Gear Solid: The Twin Snakes: It was remade for the 'Cube. Now, I wanna see it remade right.

StarFox: Just upgrade the SNES/N64 version's graphics and voice. The gameplay is timeless.

DOA Extreme 2: That game is impossible to masturbate to.

Silent Hill: Scared me more than any other game had before. Time hasn't been good to 1998's scariest game.

Wave Race 64: Still the best Jet Ski game ever. Bring it back with current gen graphics, and I'm sold.

 This looks like it would be my list.

Also would add

Wing Commander 2

Ultima Underworld 2
