My first thought on this was good for standing up for your intellectual property. Second thought was along the lines of trying to come up with a movie or movies that are somewhat similar to Bioshock. The only thing I got out of that exercise was 'Dark City' a very difficult to classify movie that came out a year before 'The Matrix' and gets compared readily to that but aside from a few themes isn't as similar as people make out. It's also a movie that I feel excelled despite IMO a very weak cast. Honestly the visuals from 'Dark City' are probably what most reminded me of Rapture.
Also as an addendum the best video game based movie to date is IMO 'Ace Attorney' an adaptation of the first Phoenix Wright: Ace Attorney game.
