Firefly Studios announces that Stronghold Kingdoms, "the world’s first castle based MMO" they announced last year, will be subscription free when it launches. The game will use a card-based system, and player will receive a set ration of cards each month, and the game's business model will be selling additional cards. "Strategy cards are integral to the game. The skilful use of a card can be the difference between winning and losing a confrontation", says Firefly creative director Simon Bradbury. "Strategy cards bring a new tactical depth to classic Stronghold gameplay, all in an online world of tens of thousands of players."
