When I'm playing 'Rock Band,' I'm like, 'Man, someday, later on in life when I'm a famous rock star...' Which gets a little harder to convince myself of as I reach middle age, but it still happens a lot.

People talk about games and loneliness - it's a lonely activity. I didn't understand that. 'Gears of War' was the first multiplayer game for me that I enjoyed. But I wasn't sad. I liked being alone. I liked playing games by myself. I had lots of companionship at the house.

I've always been a proponent of the idea that technology doesn't matter to game design. The example I always like to point out is 'Tetris,' one of the greatest games ever made.
