I'm not that big on the idea of remakes. Most of the games that I loved back in the day still hold their appeal for me today. Also, in some cases, I think remaking a game with modern graphics would rob it of some of its charm. For example, Fallout 2 had very few character models (eight, I think, according to one NPC in the game who was breaking the fourth wall), but some of the characters had interesting or amusing descriptions when you used to look cursor on them. My favorite was the guy in the Hole whose description simply reads: "This guy only has one tooth!" I actually really enjoy using these sorts of descriptions to visualize the characters.
Planescape: Torment is another game for which this would be the case. There was a ton of descriptive text in that game, and it would most likely be lost in a modern, 3D remake. There is no way that the scene where you ask that one lady to cut you open and go rooting around inside you looking for loot would be even half as funny if it was rendered in a cutscene with modern 3D graphics, instead of being explained entirely through text.
That said, I think I would be interested in seeing the KotOR games get remade with better combat systems. In both games, I found combat to be a boring time sink between the interesting stuff (and I don't thing anything would be lost by upgrading the graphics of these games; they had already made the jump to the modern, cinematic approach). Similarly, while I still find Dark Forces fun to play, I think it could benefit from a combat upgrade. The innovation of using WASD + Mouse is much better for FPS games that the old arrow keys + autoaim system was.
