Typically, Valve makes downloadable content available free, and Redmond will be charging 560 Microsoft Points for Crash Course -- or about $7. Faliszek went on to conclude that while Microsoft handed out the first Left 4 Dead DLC free, it might be unfair to everyone else. Valve's upcoming Team Fortress 2 DLC will also have a price on it.
Last year, Valve's president Gabe Newell said, "On the consoles, they want us to charge money for [DLC], because that's in their model, and our model is very much more to grow the community by giving out free updates." While I can understand charging for DLC -- $7 seems a bit steep for a bit more content which has little overhead to distribute.
