Re:Wolfenstein vs Doom vs Quake (Score 0)

Perhaps I'm being a bit nitpicky, but you are slightly incorrect about doom. Sectors in doom can be whatever shape you want, even hollow (think donut) It is the subsectors, generated while making the BSP tree, that must be convex. The BSP tree system utilized in Doom was in and of itself a technological breakthrough, which, while transparent to the player, makes a world of difference in terms of performance.
