The only thing I don't like about this is that Steam is absolutely required. GFWL never was. With Fallout 3, I never logged into GFWL even once until the DLC was released. Then I logged in to buy the DLC, then logged out. I didn't even have to log back in to run the DLC, all you have to do is move the data files to the Fallout directory and you are good to go. Can't do that with Steam, you absolutely HAVE to have it. Still, it's not a very obtrusive form of DRM, and at least there are no limited activations or continual online requirements.
