Um, NPCs make maps more than just a bunch of empty rooms. Enemies, civilians (if Outcast/Academy had any) and allies are all NPCs.
Because it doesn't directly involve the making of a map, doesn't mean knowing everything you can about NPCs, and other extentionalized data - in fact, knowing as much about the game, allows you to make better maps and levels than otherwise.
I don't like quake, never liked quake, and don't like Star Wars quake. So basically jk2mp.exe never gets used on my computer.
