I get bored of games after 1 playthrough for the most part.
Only my favorites games or creative playthrough games get more time.
The same is true for books, movies, tv shows. As for songs, I get bored of them quickly too, but they take a few more tries. However much less times then most people in my experience. Even watching someone play a game, will make me not want to play that game, because I feel like I already played it.
So even though Bioshock had a great campaign, I only played through it once or twice and thus it had no replayability.
