Now, we usually hate posting when street dates are broken, because, you know, they usually get broken. Heck, so many get broken that someone really should register brokenstreetdate.com. Now, downloadable content, this is new.
At time of posting, GameStop is already selling a retail packaged version new Fallout 3 DLC, Point Lookout. This downloadable content is not due to hit Xbox LIVE until next Tuesday. The retail codes that GameStop are selling right now work, so people are buying this and people are playing it.
And since codes work early, expect this to happen more and more and more.
Usually Ships In 24 Hours [GameStop Thanks, SmllTwnTheory!]
