As you probably know dragonville or the town near spawn has been leveled to make way for Metropolitan International Airport. Work has already begun. The purpose of the airport is to connect Corravista, WestSpur and Orca Ville via an airport.
While it is as useless as highways (due to the lack of vehicles other than minecarts and boats, both of which cannot be used in either situation and location), I would like to see how it would turn out, I have never seen an MC airport before.
So do a lot of mine carts cause a lot of lag? Before completely getting rid of the idea please let me show you a small scale model to show what i mean.
