Bioshock

Well the Retail version will probably feature Securom v7.xx and I know it has an activation. It contacts 2kgames server and autopatches/decrypts (probably) before you can play the game. So anyone who managed to get the PC-version form a store pre-release-date (ohio anyone...) can't activate it anyway.

Steam version will of course feature Steam "protection" and possibly 2k activation server..

all the online authentication check does it make sure you have a legit dvd in the drive. you do not enter your key until afterwards when there is no longer a requirement for internet. I checked my timestamps after it authenticated and the only file that was edited was the exe.

Edit:
Looks as if the Direct2Drive version will use ActiveMark with online activation.
