RJ-RotWK brings the best from each title in the BFME series by EA. As a mod for Rise of the Witch-King, at it's heart it brings 3 new factions to the game. Men of the West has been broken into Gondor and Rohan, with new heroes, units, powers, and more. Arnor has also been fleshed out to be a unique faction with a mix of Men and Elves and more. Men of the East and Mordor has also been split, with Men of the East made up from two smaller sub-factions of Rhun and Harad. The Elves are now made up from three smaller sub-factions of Rivendell, Lothlorien, and Mirkwood. In total, over 70+ new units/heroes/structures and more have been added. Over 20 new maps are included, and much more.
This is a mod that adds vast amount of new content to the game while still maintaining the original playing style. After you have gotten bored with the original game it is a mod you can play for hours on end without realising it. It may be slightly unfinished but it is by far one of the best mods for RotWK.
