So, dear Mr Pete Hines and the other important people @ Bethesda, have you found out that the Pc version of the game is already pirated? I , a legit buyer of the collector's edition am still looking in my mail to see if the store has shipped the box, while the pirates are already playing and bashing your game all over the internet.
If piracy is the real reason you didn't put all the game on disc for Pc, then I'm afraid it didn't work, so I hope when you release the next game you ship most of the content (maybe 99%?) so as not to torture your legit buyers who don't have good internet with humongous downloads, after all they chose the retail version for a reason! GTA V shipped with 5 or 6 dvd's and I applaud them for that "tiny" detail. Activation by Steam is already a sort of drm.
