I'm buying the full game when it is released. If they let me download it or buy it from a retailer to get all the bonus content, I will. I know this game will eventually have a package to allow me to play KI 1 and 2 arcade versions.
This whole issue of the machine being always on, the DRM issues, really doesn't bother me at all. Our Smartphones are always on (even when you power it off, it can still be turned on); can listen in and record us; all our clicks can and are logged and we are forced to be signed in to Google or Apple just to use the apps.
Nothing shocking or new about this system. Sony will eventually fold to the same platform too, either during the life of this console, or the next.
