Ken Levine has been working on the BioShock franchise exclusively for nearly a decade at this point. When asked straight out if he yearned for a new challenge as a writer outside of the BioShock franchise, Levine was frank in his answer: he doesn’t know.
“I always do like mixing things together, but I don’t know. Because I haven’t thought at all about what the next game will be…” said Levine. “We’re working on DLC and after that I don’t know… Games are such a big investment that people are putting a lot of faith in you and I take that very seriously.”
