Firefly Studios has announced Stronghold Kingdoms, a 2010 dated castle and kingdom MMO. Although they don't currently have a publisher, the Stronghold series is well, for lack of a better term, strong -- we have no doubt it'll find a happy publishing deal in the coming months.
The game itself will be very familiar to fans of Firefly's previous works, with lots of besieging, battling and pillaging -- after the proper bankrolling of course. We'll warn the faint of heart now: delve into the official website at your own risk, this is not a casual game of "Let's build castles and play armies!" that Firefly creates. On the contrary, this looks to be a game with enough depth to drown a giraffe twice over.
