[Slightly off topic]
Observe this pattern:
Wolfenstein 3D, Spear of destiny, Return to castle wolfenstein
Doom, Doom 2, Doom 3
Quake, Quake 2, Quake 3
If you ask me, Quake 4 doesn't belong in there. It breaks the pattern.
(Not counting the other less known games, and the slightly more known games in 2D)
