I have created a "mod" of Rome 2 that makes absolutely no changes to vanilla. There is no file to download. It is vanilla. However, I have changed things to resemble the world of GoT/ASOIAF. It is a complete immersion. I will explain in more detail and send the files (a word doc and an image of the Rome 2 map; no game files) to anyone interested, but know that I only do roleplaying campaigns (meaning, we become the faction, instead of ourselves).
