1985 saw the release of a roguelike (pseudo-graphical) MUD called Island of Kesmai on CompuServe[18] and Lucasfilm's graphical MUD Habitat.[19] The first fully graphical multi-user RPG was Neverwinter Nights, which was delivered through America Online in 1991 and was personally championed by AOL President Steve Case.[20] Other early proprietary graphical online RPGs include three on The Sierra Network: The Shadow of Yserbius in 1992, The Fates of Twinion in 1993, and The Ruins of Cawdor in 1995. Another milestone came in 1995 as NSFNET restrictions were lifted, opening the Internet up for game developers, which allowed for the first truly "massively"-scoped titles. Finally, MMORPGs as defined today began with Meridian 59 in 1996, innovative both in its scope and in offering first-person 3D graphics, with The Realm Online appearing nearly simultaneously.[20] Ultima Online, released in 1997, is often credited with first popularizing the genre,[20] though more mainstream attention was garnered by 1999's EverQuest and Asheron's Call in the West[20] and 1996's Nexus: The Kingdom of the Winds in South Korea.
