Haha, are you playing Warcraft like a secret alcoholic?
I think about some of the games that were fun decades ago, but my chief obstacle is that they would just obliterate vast quantities of time.
I played the original WOW for a few months back in 2004-2005. I would sit down to play around 6:00 PM after work and I would look up and it would be close to midnight.
Tangential but the one game I really miss was an MMO that preceded WOW - Asheron's Call. It came out around 1999-2000. That game was also a time destroyer. It had randomly generated loot, within certain ranges. You never know what a mob might drop, so it was easy to get caught killing "just one more."
