I finished the game last night. Overall, I liked the game a lot. There are some nice touches with the ending I quite liked. I won't go as far as saying my mind was blown since I didn't find the ending that surprising, but I did like how it unfolded.
I may not play it through again though. I did with the original Bioshock since how you treated the little sisters changed the ending, but there is no similar choice in this game.
I loved a lot of the easy to miss aspects like the music and why it is there. I also loved the whole hall of heroes portion.
I loved Fortunate Son
