From the introduction: An interpretation of the Ultima: Age of Darkness Games (1-3) These rules and settings use content from the first three Ultima CRPG games: Ultima I – The First Age of Darkness, Ultima II – Revenge of the Enchantress and Ultima III – Exodus. These three games were released from 1980 through 1983 and formed the basis for the wildly popular Ultima series and the Ultima On-line MMORPG.
