Historical RPG Kingdom Come: Deliverance isn't out for another ten days but modders are already working on a Game of Thrones total conversion mod. The mod, called Seven Kingdoms, will feature a role-playing story set in the Riverlands during the War of the Five Kings, and it's from the same team that created the Game of Thrones conversion mod for Total War: Attila. 

The modders are halting all work on the Attila Seven Kingdoms mod and focusing their efforts on Kingdom Come: Deliverance because the RPG is better suited for the project, they said. "While we were able to bring the main armies and characters from Game of Thrones into Attila: Total War, it offered very little modding support and potential for new features. For example, a campaign set in Westeros could not be created," they said in an FAQ.
