Jeese.
First it was Starcraft. I didn't do the dumb 3vs3 and whatnot, I RPed (Role-Played). So many hours... Once RPed for 10 hours straight with some friends one summer vacation, and we actually finished the RP (for those that don't know, finishing a Starcraft RP is near impossible without dedicated people)
Second was Morrowind. <3 that game. Until I got Vampirism, didn't know how to cure it, and killed everyone in the whole fucking world XD good tiems...
Third, Runescape for the LOOOOOOOONGEST time. Until I got tired of trying to grind levels.
Fourth, Diablo 2 for an even LONGGGGGER time.
Then Oblivion, proceeded by COD 4, then FO3, and now COD 5: WaW
Im sure once Halo 3: ODST and MW2 come out, that'll suck me into another vortex of life-wastery.
Thankfully the Subscription fees keep me off the WoW grindfest.
