Eye of the beholder
Several remakes of the original game have been created as modules for Neverwinter Nights.
Two similar games, Legacy and The Quest, have been produced for the Pocket PC and Palm by another company, Redshift. These appear to use some identical wall textures and even map sections.
There were also two official sequels to Eye of the Beholder : Eye of the Beholder II - The Legend of Darkmoon and Eye of the Beholder III - Assault on Myth Drannor.
