IMO the main use for 3ds is to build stations. It would be cool to have choices of different stations without having to build them. Just simple little stations that arent as ugly as the ones in NL right now (the woodie one isnt too bad).
Just a thought, please noone give me the "or you could not be lazy and build your own station" statement. If you do ill put a rabbit in your underwear drawer and he will poop everywhere, little rabbit poops, which we all know dont taste as good as they look.
