3D First-Person Games, So Far

Gernot Ziegler writes: "One of my professors (Stefan Gustavsson) has written a good summary that explains the history & technical background/innovations that Doom, Quake & Unreal brought with them when they were released. Check it out." It's a pdf file. Gustavsson ends with a list of hopeful questions about where such games can go, after nearly a decade of running and violence. What I'd really like to see is a goal-free 3D world like the Snowcrash Metaverse, but it will take games to get there ;)
