This is a lot of small structures that me and my friend made. You start in the "middle" of the map an underground cave with minecarts all over it. You will see signs to where the railways lead. Just wait for the minecarts to come and then go to the place you want (if you dont wanna wait for minecarts and you have SPC or Zombes fly mod just follow the railway while flying)

These are the stuff that currently is in the project: The Castle, The House (with dogs), The Farm, The Docks (The docks minecarts are a little bugged), The Big House + Garden and The Amusement Park.
