I rarely get excited about FPS games

I loved the first Bioshock and played it through twice back-to-back to experiment with the endings and multiple approaches. But I still haven't gotten around to Bioshock 2 as I can't quite appreciate the concept of being a Big Daddy plus the aesthetics and gameplay just make the game look more of an expansion pack than a stand alone game which can be defined on its own merits.

But the third game does look really good, it could rival the first one.
