Just started this game a few days ago. I'm not sure yet how I feel about it. A LOT about this game is different from the previous ones.
I'm not too happy about the remapped controls. I think Bioshock 1 & 2 had a really great control scheme and I think changing it was a bad idea. It's not a big change, but it's just different enough to be annoying. I also think the "message" of this game is a lot more ham-fisted than the first two. Bioshock was 2K's big critique of Objectivism and Bioshock 2 was 2K's big critique of Collectivism. Both were insightful and thought-provoking in their own way. Bioshock: Infinite is 2K's big critique of Evangelical Christianity, but instead of feeling intelligent and deep, this just seems like a crude caricature. I haven't gotten terribly far yet so maybe the game will surprise me, but so far it's making me grind my teeth.
I like the fact that we've finally split away from Rapture and Andrew Ryan. I didn't think I was gonna like it, but I do. I'll miss the Big Daddies and the Splicers but I think 2K had just about plumbed the depths of what Rapture had to offer in terms of story. I'm glad they let Rapture go out on a (relatively) high note and moved on to something new. I also like the fact that we actually get to see the new city of Columbia before everything went to shit. And I especially like the mystery of who, and what, Elizabeth really is.
