As I've mentioned in other threads, Bioshock: Infinite isn't just a game, but also an experience; and, an astounding one at that. After playing the first two, I had great expectations for the title, and I wasn't disappointed. From the stunning visuals to the fluid, balanced gameplay (mind you, I played on hard), everything seemed to really work.
It almost goes without saying that Bioshock: Infinite isn't an action-based game per se, but more so a story-centered one. Quite frankly, I'm surprised that you had this reaction to the story as I find it to be nothing less than epic. With discriminatory undertones prevalent throughout the story, as well as there not being any cliché romances that oversaturate the story, it's nothing short of art.
In case you can't tell, I loved it. I'm quite shocked that you had this reaction to it, but maybe it's not for everyone I suppose.
