IT got real bad for us at my last job. Of the 15 techs, phone guys and network engineers 7 of us played. It got to where we didn't talk about anything else on smoke breaks or lunch. We researched during work, and the boss almost started firing some people because they would stay up all night and either show up late, or call in sick, and then we would find out they were playing.
Luckily I had set strict rules on myself for playing, and was always gone on the weekends. I never became godlike, but when I looked at my research last night, I had to hang my head in shame. 3 different binders full of maps, quests and other assorted items.
I do want to get back into it, Diablo II is cool but just gets old when you compare it, AOLII is just about the same as far as getting old, the only things we keep out to play are Roller Coaster Tycoon for my girlfriend and the games like Life and other boardgames that we will play together.
