G.Q. leads a discussion concerning the origins of DLC, and the future of this somewhat controversial revenue stream. Once upon a time, we had to work to unlock new features in the game, upping the replay value for already purchased content. Now instead of hard work, you just need to shell out an extra $5-10 dollars. Is it worth it? Does DLC add anything substantial to the game or is it just a way for companies to milk more money out of you.
