Disclosed herein is technology for extending a user's play of a realm-building game. A user playing the realm-building game may have an existing realm built from one or more basic assets. A value may be assigned to the existing realm based on basic assets used to build it. Then a difference may be determined between the value of the realm and a threshold value. If above the threshold value, the user may be offered the option to improve the realm for a cost. The cost may be based on the difference between the value assigned to the realm and the threshold value. If the user decides to improve the realm, the realm may be removed, including all assets used to build it and the user may be provided with one or more advanced assets to build a second realm.
