EverQuest, 16 years. I also dabbled for a short while playing EQ2 when it emerged. I have never played WoW, Final Fantasy, or other noted games. When not feeling overtly social, I have also found great joy in playing most every Sid Meier game ever produced during the last 20 years. Most recently I have been playing Project: Gorgon like a fanatic, while waiting for Project: Gorgon, as was mentioned originally, by SNOWE. As for Asheron's Call, I loved it, but I simply had too much invested into EverQuest, so Norrath continued to be my main MMO world.
