I see some playerworlds out there with gigantic overworlds. The one I'm making is 10X10, about 100 outside levels. So you know I kind of favor this rule.
You could stick quite a lot in one level if you think about it. Have like at least 4 or 5 small buildings in a level and fill them in.
I think this rule should actually be considered. It sounds like a very good rule me. I guess that's all I have to say.
