Yah, it's kinda boring.
Say, have you ever tried out using MOHRadiant and making a map. I'm working on the 12th update for my first one. It started out as my dorm building at college, which is a 4 story with a basement building housing about 85 rooms. Now it includes the surrounding area of the building, including all the different terrain heights, the running creek in the middle, some exploded vehicles, and another playable dorm building across the map from mine. The other two dorm buildings make appearances on the map, but are not enterable. It's goin pretty good with the map editor, but some things just take so frikin long.
