I love the Bioshock series (guess it's a series now that there are two of them), I really do. I've completed them both, and am tempted to start the first one over and do through them to get the other ending (won't tell you which one I got the first time). After I'd completed the second one, I began to analyze why I like them so much. Is it the first-person shooter? Nah, I like FPS but that's not really a big deal. They made some updates to the game play for Bioshock 2 (some pretty cool ones, too),...
