The price of creating an alliance is equal to the sum of 60 days of plot rent. Collaborate with other players to help make the road to owning a successful business less bumpy and much quicker. You can even ask your friends to join your alliance or make some new friends in the game. They can help you with cutting wood, producing iron plates, or tools in exchange for something from you. Cooperation like this will make your way to the goal much shorter, more efficient and much more enjoyable.
As you can see in the screenshot, to create an alliance you need to give it a name and choose a color scheme.
