Could it really be? According to Destructoid, 2K Games may be working on a MMO game based on the Bioshock franchise. This wouldn't be a complete surprise, since Strauss Zelnick, Take Two's boss, said a while ago that they plan to explore the MMO aspect in series such as Bioshock and Civilization.

This may be just a rumor, but how would you feel about a Bioshock MMO? Wouldn't it be somewhat against its nature to have Rapture - or a similar setting - invaded by hundreds of real players?
