Very good list, especially Undying and Eternal Darkness.
I would add Star Control, if you're looking for games with great writing. StarCon II still holds up well today. We won't discuss SCIII, as the change away from the original IP holders led to a serious quality deficit.
Agree that TIE Fighter II would lead to many old gamers keeling over dead. Probably a good thing that LucasArts isn't looking into anything that awesome and perfect.
To my mind, there is a real treasure trove of old IP in some of those old companies like Bullfrog (Dungeon Keeper, Syndicate, Populous), Looking Glass (Underworld, Terra Nova, Bioshock...er, System Shock), Origin (Wing Commander, Ultima, Strike Commander). I've never been able to figure out why devs would spend years and millions on developing new unproven IP when there are such devoted fanbases pre-created.
Just look at the fantastic reception that Bethesda has gotten for Fallout 3. I think they are over 500M in total revenues already (correct me if I'm wrong, folks who have active subscriptions to NPD). This is IP that was 10, count em, 10 years old, and it's selling like gangbusters. Take it, dust it off, put your A talent on it, and collect 500M. Pretty good deal.
