As of the latest update, the mod 'has pretty much everything in it' that the team had planned for V1.0. We've been posting about the Game of Thrones mod for Crusader Kings 2 for years, but if you've been holding out for a more stable version then I've got some good news. Open the 'CK2-icefiremod-1.7.1.zip' that you just downloaded and copy the 'A Game of Thrones' folder and 'A Game of Thrones.mod' files to your mod installation folder, normally My Documents.
