HELLO. First post here. Couldn't help but come after playing ant.bsp! I still love Q1 and have just now been looking into how to build maps. One of my first ideas was for a labyrinth... I thought, wouldn't it be cool if a SP map looked like this??

then I realized how fast the strafing and running is in Q1, and you almost never see tight corridors. So I can't decide, but if I knew of other maps like it (surely there's been a lot of mazes for the Quake series, DOOM, etc?) maybe I can see how it works. The Doom games had more maze-like levels... but i'm mostly interested in Q1.
