umm... yeah, but other games like NWN have lever editors, and using them i have never gotten bored. Perhaps you could make presets, for example forest1: it contains lotsa trees and you just place it somewhere. same with the houses, make one, copy it, extend and decorate the copies a little etc. and voilla. And you wouldn't have to make such large maps as rivertown or dark forest...
BTW what game are they working on right now?
