No purchase is required to have a full game experience. In Offline mode, all game content is available in-game for in-game gold. Crowns of the Obsidian (COTOs) can be used in-game to acquire exclusive items and services.
Don’t forget! Hometown is an amazing resource for players. At Hometown, (located just east of Soltown) players can examine available houses, Player-Owned Town templates, and even new Crown Store items. Why not be certain you like it before you make a purchase? So head on over to Hometown and check things out!
