My MMO Is My Castle: Stronghold Kingdoms

Firefly Studios - they of the castle building/sieging series, Stronghold - are making an MMO, Stronghold Kingdoms. The game will encompass medieval Europe and allow players to build a series of castles, and their attendant settlements, in a wide-open strategy game in which crushing your enemies will no doubt play a vital part. Firefly describe the game as "a mix of real time gameplay with long term planning", in which there will be opportunity to "Build, Besiege, Pillage, Farm, Explore, Research, Vote, Trade, Banquet, Fight and much, much more." The game is apparently being developed by Firefly Studios independently of a publisher, and is due some time in 2010. There's a smidgeon more detail on the official site.
