The step-father of a friend of mine has been playing it 80+ hours a week since it came out. I've never not seen him playing it. He's skipped work to play it. It's kinda creepy.
I use to be hooked on SG. A recent, forced offline period got it out of my system. I'm going to try to get back, again. If my life force is going to be sucked, it might as well get sucked here. -insert suck joke here-
I'm actually forcing myself not to play it...I'm just now starting to get out and get healthy, and not spend every waking moment in front of a computer or TV screen...
