After a short-lived instance of ''GemStone II'', ''GemStone III'' was officially launched in February 1990. ''GemStone III'' became available on [[AOL]] in September 1995, followed by the release of ''[[DragonRealms]]'' in February 1996. By the end of 1997 ''GemStone III'' and ''DragonRealms'' had become the first and second most played games on AOL.{{R|dunin-simutronics}}
