If they were to re-release a game and not change a thing except update graphics...
 

...fix obvious bugs and dialog errors, and I suppose add network support in split-screen multiplayer games.

Lots of games have been remade/updated but it's more often miss rather than hit. Aside from the remake of the first Resident Evil, I don't know of a single one that's been critically acclaimed.

Which game would you choose?

Final Fantasy VII is the obvious choice but I want to try to be original here.

Twisted Metal 2. Can't even put my finger on what's so great about that game as I'm not even a gigantic fan of the franchise, but I loved part 2 so much, I'd love to see that particular game remade.

The Ultima series up to VII part 2 the serpent isle.

Commander Keen

Daggerfall

none, i hate re releases even if its just a graphics update.

Even FFVII I would not want to see redone, i loved those blocky graphics its what i grew up with its how i remember it. Re releases are just a poor way for multi million dollar companies to try and make a few extra bucks, instead of taking the time to make a new game they take an old hit redo the graphics and put it on the shelves. Lazy and disgusting.

Mechwarrior 3
Interstate 76
hmmmm, that's about it

Majora's Mask. =>

I want to see a remake of Legacy of Kain/ Blood Omen. I fucking love Kain. He and LeStat are my top favorite vampires. Nobody beats Kain though.

I also want to see a remake of the first Oddworld. Most PS1 games were really unique, and fun. I kinda miss em.

As far as a computer game re-released. Mmmmm HoMM 2 and 3. Icewind dale, and Rage of Mages.

Leisure Suit Larry.

Planescape Torment is the obvious choice or I'm even thinking Starsiege
