Alter Aeon has been under active development for more than 15 years.
Alter Aeon began as a multiplayer text game in early 1995. In the late 1990's, the blind and visually impaired began to access the internet using screen reader software; as a text-based game, Alter Aeon was well suited to this crowd. Since the year 2000, there have been many updates to reduce barriers and improve the gaming experience for both blind and sighted players, with the development of a custom MUD client and player-contributed sound packs.
