Yeah, good thinking. I especially agree with Quake on the list. It would be so cool to see a true remake, one that has a very similar style and feel as the original game.

It's sad to see that a lot of developers try to do 'something new' with the sequels. Take Deus Ex 2: The Invisible War... I mean, they ruined the RPG part, made it a more generic almost console-like shooter. The first game had a very unique style, a matrix-meets-james bond kind of style, sci-fi at it's best.

Cheers
