You Are A Potential Thief
Rumours surrounding the Bioshock copy-protection suggest that you'll have to reinstall the game from scratch if you change any element of your hardware configuration, and that you'll need to be online all the time to play at all. If your net connection goes down there'll be no underwater adventures for you. I can't find the relevant Gamespot thread, so this is just specumalation.
Yeah, okay, I'm posting irrelevant waffle, but in some way I hope this is true so that I can post extra-indignant things on the internet decrying our loss of convenience/privacy.
