You can become a Big Daddy in PlayStation Home ... if you pre-order BioShock 2 on amazon.com. The online retailer is offering the game, $10 credit and exclusive access to this Home costume for $55. It's the perfect costume to wear if you feel like picking up chemically engineered underage girls in Sony's online community. If that doesn't entice you, there's always GameStop's pre-order incentive of extra multiplayer characters. [Via @amazongames]
