One of the games we're looking forward to playing next year is Earthrise, a post-apocalyptic MMO currently in development at Masthead Studios. At launch, Earthrise will offer guilds a wide selection of buildings and facilities that can be built within their controlled territory. Masthead Studios has bigger plans for city building and Territorial Conquest game mechanics post-launch, though. Long term goals for this aspect of guild-level gameplay include expanding options for guilds to become less beholden to the major NPC factions (and the cities of Continoma and Noir).
Specifically, Masthead Studios would like for players to establish administrative buildings, which will provide some of the conveniences and features generally found only in NPC-held cities. According to the Earthrise devs, "Administrative buildings will remove the requirement to visit cities even further by providing access to Market, Warehouses and more from inside the Guild owned territories."
