What games from years gone past do you reckon should be redone today? Why, and what would you change if anything?

Here is my preliminary list:
The original Dues Ex. Loved the games to bits. I reckon that with just some new graphics that game would be good to go.
Syndicate of course. The isometric version.
Jagged Alliance. New one coming out soon. (not on consoles though :-( Would love to be able to play that again.
Both the System Shock games. Graphics update of course. Think the rest of the games should stay as it is. Perhaps a co-op mode would be nice.

Those are my 5 for now. Will ad more as I think of more.
