I once played Diablo II for like 11 hours straight... (I am never going to play an online RPG again)
I could see oblivion become the game I spent the second most time on... (Diablo 2 would be #1... I put over 500 hours into that)
End of 2009 Predictions (Set, January 1st 2009)
Wii- 72 million 3rd Year Peak, better slate of releases
360- 37 million Should trend down slightly after 3rd year peak
PS3- 29 million Sales should pick up next year, 3rd year peak and price cut
