Bioshock Infinite

So, I have finished Bioshock Infinite. I shall not spoiler it. However, the people who truly had their minds blown by the ending simply don't read enough SF - it's all fairly standard tropes, albeit in a very well presented package. Also, it dicks with the 4th wall in exactly the opposite way to Bioshock, which I thought was kind of cute.

I did not anticipate the final twist, but I feel this was largely due to an Agatha Christiesque withholding of the crucial information necessary to piece it together properly.
