I just got it yesterday from amazon.co.uk, I have to say it is quite a good game. I am really not a fan of the mini games and it is not as free form as I thought. It gives you an illusion of freedom rather than actual freedom.
Also I would say it feels like a film(or TV series) rather than an actual game, it cuts between cameras just like a film.
I find it starnge that the US version has been cut, the game recieved a 15 certificate by BBFC, which I guess would the be equivalent to an R certificate in the US. I really see nothing wrong with what I have seen in the game so far.
