Social MMO specialists, Bigpoint Games are attempting their own Game of Thrones adaptation. Unlike the two Cyanide-developed Game of Thrones titles, Game of Thrones: Seven Kingdoms focuses directly on the television series (that's right, the most recent Game of Thrones RPG wasn't tied to the television series - if you'd read my review of it, you'd know that), and it's a free-to-play, browser-based MMO.
Game of Thrones: Seven Kingdoms is set for release some time next year. In the meantime, you can check out the new teaser video and screenshots.
As Gaming Nexus's resident A Song of Ice and Fire expert, let me just say that may the Others take them if Game of Thrones: Seven Kingdoms isn't any good.
