WoW, not even close, 3 85s, 3 80s, the other toons above 70... just sucked my whole life up. I play it when new expansions come out, but then I quit again because I get bored. I used to raid all the time, 5-6 nights a week, but now I have a girlfriend so my time is utilized in other ways
Before that it was Counterstrike/Half Life/Unreal Tournament etc, big into FPS before Call of Duty became the end all be all it has become.
Outside of that I absolutely loved Final Fantasy games. I logged so many hours on FFX because of its story and ability to cross train your characters in almost every single sphere layout. Can't wait for the remastered FFX, whenever the hell that comes out.
