Angband is a freeware computer dungeon exploration game based (loosely) on the books of J.R.R. Tolkien. You explore a very deep dungeon, kill monsters, try to equip yourself with the best weapons and armor you can find, and finally face Morgoth - "The Dark Enemy".
Angband has a very long history. It started in 1990 as an improved and "Tolkienized" variant of Moria. Moria itself was created in 1985 and was inspired by Rogue (from the late 70s). The first version of Angband was created by Alex Cutler and Andy Astrand at the University of Warwick. The notable maintainers in the 90s were Charles Swiger and Ben Harrison. In 2000, Robert Ruhlmann took over. Starting March 2006, the game was looked after by Julian Lighton, and since April 2007 by Andi Sidwell. Starting the release of 3.5.0 on Christmas Day 2013, the game is maintained by Nick McConnell.
Angband is a member of a family of similar games called rogue-likes. Other well known games of this type are Nethack, Slash'Em or ADOM.
It's addictive, very addictive. Your REAL life will be influenced by playing! Don't say I didn't warn you! Angband was originally text-based, but graphical versions are now available for almost every computer system. Some Angband players still use the old ASCII-based graphics. There are even a few sound effects available for multimedia freaks ;-).
The original name "Angband" was created by J.R.R. Tolkien in the stories about "Middle Earth". Angband was a mighty fortified citadel originally constructed by Morgoth (Melkor) in the earliest days of the world as an outlying fortress to his northern stronghold of Utumno. Utumno was destroyed by the Valar, and Morgoth imprisoned in Valinor for three ages, but on his return to Middle-earth, he took Angband as the seat of his power, and raised the towers of Thangorodrim above its gates.
Angband was besieged by the Noldor during the early part of the First Age, but the Siege of Angband was broken at the Dagor Bragollach. It was finally destroyed by the forces of the Valar at the end of the First Age, in the War of the Wrath.
The details of the story can be found in J.R.R. Tolkien's book "The Silmarillion". You can also take a look at the entry for Angband in The Encyclopedia of Arda.
