Because we're in V21 now, there are no more interior maps. That means you have to hand make all of the terrain and ridiculously large anythings you want. There needs to be a simple way to "Put a mountain there and there, maybe over there too" without large amounts of time being spent building. Or to automatically make a road (straight lines only kids) from point A to B, and it automatically makes an intersection when it meets another road. I'm not sure how possible this could be, but it'd be nice to drastically change the look of stuff in a short amount of time. Or to put a tree, or maybe even a forest down quickly.
