The only problem that I have, with this kind of DRM, is that in three or five years from now that I am going to re-play a game (or even play for the first time. I have yet to play, Mass Effect or Bioshock), I may not be able to activate it. So something must be done by the publisher and/or the developer, to ensure that the game is still activated after some time has passed. (Remove the DRM or keep the activation servers online or even do what Derek and some other developers do, when they release their games for free, after some time has passed.)
May be that's why I am going to buy it. But I thing that I will wait for the collector's edition (which it will contain all the inevitable add on packs )
This may have a lot to do with the kind of games they make and the age group they target. Although they use a kind of DRM. (Impulse or their way of patching the games).
All in all an excellent article. Especially the part about the economics of the torrent search engines.
