I think that may be a little harsh when you don't know them personally or the circumstances. I'm not saying I spend that much time playing a game. Perhaps they just got caught up in the game for one particular mission and stay on until they beat it. Maybe they were bored with nothing really to do at 1:00 and just kept playing, but to sit back and look down on someone because they don't do what you do is also pathetic. Which I am not saying you are this way, but there are people our there with these sorts of opinions... maybe you just have used a bad choice of words, and it came out wrong.
I, myself sometimes sit down and watch movies back-to-back for maybe 10 hours or so, is that really any different?
