I don't understand why people think every room has to have a 3 page description. A room's description ought to depend on its' importance. For example the lair of the evil priest king which can only be traversed through hours of mazes and fighting dragons and finding hidden keys, should be long, but one of the many side streets in Typical Town should be concise. Now I'm not saying a one-or-two liner necessarily, but something like 5-8 lines. And for unimportant filler rooms, not even uniqueness is really all that important. If you make a town or other type of area where EVERY room, including "paths from one significant point to the next" which are just filler, has a huge and unique room description, it just becomes a burden to read it all.
