That sounds like a recipe for a cramped hallway of a map; how about each sector has to have at least 4 or 5 other sectors directly adjacent?

That's sort of the idea though, seeing what kind of variation I can get from hallways and small rooms. I do like the dynamics of fighting in hallways, the danger of projectiles being increased ever so slightly. 256x256 is a pretty decent space too, as you can fit around 60 human-sized guys in one 256x256 box, not that anyone would but it's interesting to note. If more room for a certain area is needed, teleporters are available.
