MUME is a free multiplayer roleplaying game based upon J.R.R. Tolkien's Middle Earth.
In MUME players can explore and live in this meticulously crafted world during its late Third Age, and possibly join the epic War between the forces of the Dark Lord and the armies of the West. The action takes place before The Hobbit and after the loss of the One Ring by Sauron. The key of Erebor was just found by Gandalf in Dol Guldur and all the epic tales narrated in The Lord of the Rings may take place.
