Troubles of Middle Earth
Angband is a roguelike dungeon exploration game based on JRR Tolkien's works.
There are a lot of Angband variants because Angband's sources were cleaned up by a remarkable person, Ben Harrison, which meant that as more people could understand the code, more people made variants. ToME, my own variant, expands upon the Middle-Earth influence and is based on Zangband 2.2.0. ToME now follows the Tolkien world more closely than any other variant!
ToME was formely known was PernAngband, but it's name was changed because of copyright issues. Almost all Pern influences have been removed in the current CVS version.
"Three Rings for the Elven-kings under the sky,
Seven for Dwarf-Lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne,
In the land of Mordor where the shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all, and in the darkness bind them,
In the land of Mordor, where the shadows lie."
"The Lord of the Rings", J.R.R. Tolkien.
