I don't mine the intentions of DRM. I'm all for game developers getting payed for what they make. The reality, though, is that the drm gets cracked and the game gets pirated anyway. So the end result is that the game costs more to make in order to put the DRM in, the user experience is often worse from having to deal with said DRM, and the pirates still do what they do. So nobody wins.
At some point (and it may have arguably already happened with some games) the consumer will be able to a get better game by NOT paying for it, simply because they will be able to find a cracked version that doesn't treat them like a criminal. (ie phoning home regularly for security, getting pissy about being reinstalled, etc.)
