If GameStop used game business had not existed, would we have so much DLC?

Gamestop is merely an organized, physical representation of the used game market. You've still got garage sales and flea markets where you can pick up used copies of video games. Let us not forget the online market as well. I think if you love the game, you will pay for the extra content unless it's very unrelated to how you play the game. Some publishers try to take advantage of the situation, which is business, but again, the value has to be there somehow.
