oh boy... yeah WoW was around 3 hours a day x 5 days a week for about 4 years. Some days were more, some days were less, and I took a few breaks here and there. That comes out to around 100 days.
I think that's the low end for wow players as well. I played it excessively for like a whole year (wake up, play, go to bed with very few obligations during that time), I have no idea how much time I spent in that game overall, because I've had a few periods like that in my life (though never that crazy)
