I don't usually like the practice of charging extra for graphics that really should be included in the original game. However, this not only includes many new faces for the Mongol empire, it also comes with a number of new unit models too. As I also bought this pack for less than a pound in the sale, it was pretty good value as it adds extra atmosphere to an already brilliant game

A minor improvement of the game. It is not essential in any measure. $2.00 is a bit price for such a minor update, but if you can catch a sale, there's not reason not to make you game more beautiful. (considering you'll spend a lot of hours in this game.)
