There is also
this mod of Rome: Total War, The Fourth Age.
I personally think it is one of the greatest mods of any game ever made. I'm hopeful that some day dwarves and elves will be playable factions on the campaign map...which will make it just about perfect.
I especially appreciate how they craft their models to be in line with what Tolkien described and the obvious care they put into crafting their mod.
Anybody who has Rome: Total War should check it out.
