Land is a special kind of asset that determines how many facilities you can build. Each land you own will allow you to build one facility. The price of land goes up the more land you already have. You can buy land the same way you buy other assets, but land cannot be sold.
Corporations will start with 10 land in the first region that an IdleCorp command is issued in. When a corporation undergoes reincorporation, the 10 free starting land will be given in the region that the reincorporation command was issued in.
Land price = 600*[1.1^(current land total-10)]
