The Fourth Age: Total War is a modification for Rome: Total War Barbarian Invasion v1.6 (there is also a version for RTW v1.5). Our aim with FA:TW is to accurately portray the lands and peoples of Middle-earth as we think they existed approximately two centuries into the Fourth Age. It is based on the works of Tolkien, and especially on his unfinished and abandoned sequel to The Lord of the Rings, entitled The New Shadow. With an aim to staying true to the works and spirit of J.R.R. Tolkiens world of Middle-earth, whilst also aspiring to original creative excellence, The Fourth Age: Total War is a must-have for anyone who loves the setting and peoples of Tolkiens mythic world. There are currently two versions of The Fourth Age: Total War available one for Rome: Total War Barbarian Invasion v1.6, and one for Rome: Total War v1.5. Make sure you get the latest patch as well as any additional hotfixes
