The Third Age mod for Medieval Total War II was released today.
Interested parties can get it
here.
It is a rough first copy of this mod and there is still much work that needs to be done bug squashing and refining but it is an impressive first release in my estimation.
It is true that visually it follows the movies...but if you play as the dwarves you won't have that problem because they were not in the movies.
(Thank goodness this was finished before much artwork from The Hobbit has gotten out.)
