If you do, you will love this.
I adored the first Bioshock and predicted the sequel to be like nearly every other game sequel, nowhere near as good as the first.
Bioshock 2 does something very rare. It manages to be very similar to its predecessor yet still prove to be different enough to feel fresh and refined. This is achieved through excellent plot, new characters an edge of your seat atmosphere that is all wrapped up in the stunningly gorgeous world of Rapture.
Computer games are like books, films and art; essentially, escapism. No other game in my opinion captures the essence of this 'escapism' better than the Bioshock franchise. Instead of living in a boring, cold Britain waiting to either be stabbed by a chav or freeze to death waiting for a bus, I am now a resident of Rapture. Yes I am being chased by Splicers throwing knives at me, being scared over and over at the sight and sound of a Big Sister and trying to rescue my kidnapped daughter. But I know where I'd rather be and I love it.
