ooooooooooooooo
ooooooooooooooOO GOD I love the Ace Combat Series! 4, 5, 0, and 6!
Anyway! Sounds good, but another idea would be to have no exit lines (possibly no celing) and have the map in sort of a loop. If you are flying straight east past a building and you are looking at your map and you reach the end of the map, your little arrow or whatever is used to represent yourself will appear on the west side and you will eventually pass the same building. I got that idea from Hellbender, a game similar to Descent back in 1995. Maps were huge so you didn't notice that you were going around in circles.
Hmmm. If you have ever seen the Descent 3 Trailer on YouTube, some scenes looked like the would was more open and not like the boring unusual mountains and canyons seen in D3.
BTW, the Descent forums here are veeeeeery slow. If you are going to fight a war, do it efficiently, unremittingly, or don't do it at all--I'm not into ethics, I'm into efficiency.--Benjamin St. John "Descent" by Peter Telep
