So... how much time have you guys spent in game, daily, on average since the day you bought the game?
I'm celebrating 7 years day to day, at almost 3000 hours clocked. I know it's not the most out there, not by a long shot, but I also did not ever leave Guild Wars running while AFK. So every single second of that 3000 hours is actually time spent in game, playing, trading, pvp'ing.
That averages out to 1.13 hours of active gameplay every single day for 7 years straight. It's a pretty hefty time investment when you think about it. Apart from work and going out, I don't think there's anything which can compare to that amount of time.
