Are you guys planning on recreating the Morannon? I know in the movies, it was a flat plain, but the battle was just so impractical. In the movie, the host of the west was completely surrounded on a flat plain, and would have been decimated, especially considering that in the book, the Mordor host attacking Minas Tirith was completely screwed over when they were attacked from three sides.
The books described that there were two hills that the Host of the West stood upon, and in front fo those hills, there stood a mire of mud and pools of water.
