Not that old but with the oblivion engine and graphics, it would be the best of all time
I have one word for you my friend, and that word is;
Morroblivion

EDIT: Oh right, and to answer the OP,
I'd like to see Fallout 1 & 2 remade (Preferably as one game, and seeing as how F2 re-used almost all of F1's resources anyway, so I don't see how this couldn't work) with updated graphics, sounds, and with a control system in which you have direct control of your character outside of battle (if only to protect the game from being totally ignored for being a point-and-click), maybe re-do combat using Valkyria Chronicles' system (It'd work great with a Fallout game, don't deny it just 'cause it's a JRPG), maybe update the sound effects, and
leaving the fucking script alone, just add water,
BOOM, instant game of the f**king year (Well, in my opinion at least...).
