I've had Bertha's experience, but with Elder Scrolls. And I have to agree with everything else said. Apply this Microsoft 'logic' to any other product. How would that go? 'I'm sorry, you have to get permission from Honda before selling your old Civic, and then give them a cut of your asking price.' Seriously?
On a side note, Yahtzee reminds me of the kind of guy in a bar I would despise, right up to the moment he was inside me. It must be some perfect combination of extreme intelligence and asshole factor. I lol'd hard at 'kill one of the hostages'.
