In front of famous video games journalist Brian Crecente (Kotaku.com), Ken Levine confessed that Bioshock really had no good ending and that it was his fault.

Levine said: "I didn't think they became that invested in what was going on,". He went on with in the game "you have this great mystery of your own identity and once it is solved the story is over."

Sorry, Ken, but people were not only interested in the main character. After you played a bunch of hours in this amazing city called Rapture, it's some more you care about. It's the destiny of the whole world, you have stepped into. And like a bad ending of a movie, people can get upset.

But there is a chance to make it better, Mr. Levine. How about Bioshock 2?
