angband - 1:3.5.1-2.4 main

Angband is a single-player, text-based, dungeon simulation derived
from the game Moria, which was in turn based on Rogue. It is
often described as a "roguelike" game because the look and feel of
the game is still quite similar to Rogue (though there are now graphical
tiles available if you dislike ASCII gaming). Angband has been in more or
less continuous development since the early 1990s.
.
The ultimate goal of the game is to develop a character strong enough
to defeat Morgoth, who resides on dungeon level 100. Upon doing so,
you will receive the exalted status of "winner" and your character may
retire. To achieve this you will need to explore numerous dungeon levels,
defeat many foes and sift through a great deal of treasure.
.
Angband is a reference to Morgoth's "prison of iron" in the world of
Middle-Earth, created by J.R.R. Tolkien.
