I recently (recently meaning back in early to mid-March) completed Bioshock 2 which is the sequel to 2008's blast of a game Bioshock. I found really nothing wrong with this game other than unlike the first game, there was really no big boss fights and the end was mixed with thousands of Big Daddies coming out you and no one but you. The minor boss fights really came in the form of Big Daddies and Big Sisters.
Course, in this game you are playing as a Big Daddy which brings a new feel to the series becauseof how different Big Daddies are compared to humans. Again, like previous games i will not review it but just give it a rating. I think Bioshock 2 was amazing and even a little better than its predecessor. But the one thing Bioshock has over Bioshock 2 is boss fights.
