Summary: I have played Bioshock 1 and Infinite, someone suggested Bioshock 2 to me I love this game even though it's not too relevant to the story in a whole. Playing as a big daddy is great! Makes you feel like that much power should've only been capable in a Big Daddy anyways.
Summary: Purchase was easy with a bargain price and activation was trouble-free. Loved Bioshock, skipped to Infinite, loved that as well. Bioshock 2 was simply superb. I think it's a great mix between the two others, with a little more emphasis on the storyline. Absolutely got lost in it and loved it. Time to play the other two again!
Summary: I played the first Bioshock when it came out on PS3 and I absolutely loved it. This one is all the good stuff from the previous game and then more awesome slathered on top of that for a pile fun that you'll certainly enjoy if you like playing these types of games. I wont spoil anything here for anyone who hasn't played the series, though I will say that on PC it really is much better (duh I suppose).
Summary: It's a good shoot and loot game. I enjoyed the story as well. I recommend playing the first Bioshock game before this one is you want to understand the story. There are lots of references to what happened in the previous game. I think the game inspires thought as it shows a scenario where a society is formed without God, government or regulation or morals of any kind. It shows what happened to that society as you, the player, try to survive being trapped there.
