haha sounds like me collecting games that don't get played at all... I been playing Assassin's Creed Revelations, trying to get ready for Assassin's Creed 3 and Halo 4... Also you should add me on PSN and I hope your game did arrive when you got home.
I started with an Atari 2600, then 7200 I think and then almost every Sega system. Then I went to PC gaming but I got tired of upgrading it to every new game I bought. In 2006, I got my first 360 because a friend said I'd never have to upgrade it!
But I've thought about quitting several times. I'd get bored with it and want to stop. In fact a couple of months ago, I told all my friends I was quitting. But my wife and a good friend told me to take a break. So I did and I'm playing again. I'm at a point where I play for fun and nothing else. And if a game gets frustrating, I sell it. I don't have the time for that. :-)
Me, I've always preferred SP games. I suck at most of them and I'd rather not be a burden on a "team", so I don't get into MP games. I do like co-op games with friends and that as close to MP gaming as I'll get. I've had this GT for almost 4 years and I still only have 4 1/2 rep stars.
