My gamerscore is not even 5k, but I play a lot of 360 games and arcade as well.
I finally beat gears of war a few days ago.
I have only beaten that, Halo1, Tomb Raider on 360(because I rented it and I really enjoyed it and wanted to beat it before I returned it), and maybe a handful in the past generation.
I only play games in 20 minute spurts. If I have a marathon gaming session it has to be a game that is tailored to ADD'ers, ie, it has to keep throwing shit at me to keep me interested(civilization, oblivion,gta/saintsrow)
DS is my perfect console, play for 20 mins before I go to bed, or play for 20 minutes during the weekend and I'm happy. Once I hit that 'sweet spot moment' where I accomplish something in the game I'm happy.
Same thing with checkpoints in a game, if I hit that one checkpoint I'm content and I put down COD4.
Online gaming is more desirable, I used to play a shiton of Everquest just because it was ever changing with people to chat with.
I have no idea how Demi does it, our brains are obviously from different make and model....
