In addition to the usual Haboob features (no trees outside the few large forests, non-buildable strip of land in front of the edge forests), there are also lakes in the corners. An extra forest also spawns in the middle on normal size and above. Regicide adds 3 Villagers and a King, while Empire Wars add another 3 Villagers. Comes in 7 themes: Asian, Autumn, Desert, Grassy, Mediterranean, Tropical and Winter.
