I'm working quite hard on an engine with an editor suitable for some game types (... first person shooters). I haven't made real 3d games in a long while and my time is very limited. But so far, there's an editor where you can draw maps:

It's a sector/portal based thing. The game only renders sectors (rooms) that are visible through the current room's "portals" (purple lines in the image, openings between two rooms) and clips the rendering to the actual portals (all to speed things up). Right now, a map has a single floor position and wall height. But that will change, and sectors will be able to have sub sectors (internal walls and elevated areas and stuff).
Here I'm walking around in the level shown in the picture above.
