That is a tough question. I used to do a lot of things when not gaming. Raquette Ball, Getting Baked (of course, I'd do that while gaming, too), Screwing, Lacrosse, Soccer...
But now, years later and married, if I'm not gaming then my wife must be home and awake. So, I'll just be doing whatever she's doing. Usually watching TV or shopping...or eating. Yawn.
My End of 2008 Hardware Predictions (console only):
Wii : 50 million
360: 28 million
PS3: 24 million
These predictions were made on January 3rd and won't be revised
