Asherons call by a country mile, took ages to ween myself away from it
UT99 for me, no idea how many hours.
iCTF weekly Clanbase league matches, cups and LANS spent quite a bit of time
Miss the days of not levelling up not having to sink your entire existence into a game to unlock a pellet gun.
I still play it since it went a one off payment and no monthly charge. Several months played on my now main. I hate to think about my other characters as well.
I still play some C64 games and Amiga games which would have massive amounts of play time such as SWoS, Kick Off 2, Dungeon Master, Football Manager, Footballer of the Year, etc.
Cured myself by selling my main (mike the deathbringer)
Was an amazing game, WoW wasn't a decent replacement

Everquest 2 for me, played it from release in 2004 until sometime around 2010/2011 when my guild disbanded and the playerbase started to dwindle. Started playing casually for the first couple of years as I'd never played an MMO before then joined a hardcore raiding guild called Unity (on Splitpaw server) where I stayed for many years. The raiding schedule was Mon-Thurs 7PM till late and then Sunday 6PM till late with a minimum 75% attendance.
