2K Boston's Ken Levine is quoted on Eurogamer expressing his opinion that if BioShock had not been successful, it may have ruined the first-person shooter genre, at least in its high-end story-driven form. He adds that many of the publishers to whom they pitched the underwater shooter shared the opinion that it would not be a big seller, and they repeatedly met with a response that was essentially: "sounds like a great idea, you'll sell 150,000 units - next." If Ken's opinion on the topic is correct, then shooter fans should be glad those publishers were wrong, because he thinks a BioShock flop would have crippled the first-person shooter genre: "I can pretty much guarantee to you that if BioShock wasn't successful, there never would have been another game like this."
