NO............ WAY! If the release date is true, I have an excuse to get my wife to get me it, since that is my birthday. Sweet.
I've been waiting for the second installment for a long time. I'm pretty sure the final remark on time frame was that it was set way before the original bioshock and some stated in the civil war era. I haven't gotten a clear review on it. The whole being a big Daddy thing looks great to me with that new addition of being able to go out of Rapture and into the sea for a little while then finding secret areas and such.
I played through the original about 4 or 5 times just to get all the achievments on the 360 version, and I did not mind, because I liked the game that much. The story was brilliant, and the atmosphere was captivating. Also, all the characters had that "crazy" to them for having lived by themselves underwater for several years with that whole Adam collection going on. The best character I think was Fontain, (I think that's his name) the guy who made you kill a few people then take pictures of their bodies for his "masterpiece" and then there was the "irony" award for killing him when he came to look at it and taking a picture of his body.
The whole game was awesome. I hope the 2nd will be as good or better.
