"Talking with MCV, 2K Games global prez Christoph Hartmann admits that the BioShock franchise could churn out five total sequels in its life, but promises that 2K won't just "cash in" on the title.
Talking about the potential for future sequels, Hartmann says that "if we spin it the right way and get the right twist of innovation, we can make six parts of it, as Star Wars did." Something that Star Wars did do, but video games are a bit different and as much as Hartmann wants to compare BioShock to Star Wars, it's clear to us that BioShock is its own beast. Just be careful 2K. Just be careful."
I can only hope.
