I think it would be cool to see like, roller coasters, ground level parking lots, new parts for highways, new line roads that are 3x longer than the ones in the game, and airport sections (lobby, bag check, boarding bridges, etc.). I also think it would be cool to have a junk yard building model (just a building that says junk yard). Finally, a city/town hall. You can't build a city/town without a city/town hall. Also, if you can, you should put up a guide telling people how to set vehicle spawns for the origional unturned vehicles.
