Even though I said it was the third part of a trilogy, this game boasts more content than the previous two entries combined. In short, this game is massive, and almost all that content is worth doing. I don't think it's a masterpiece like other reviews on here will have you believe, but if it looks like something you'd enjoy, then you most definitely will.
I'm not sure if it's some sort of compatibility issue, but this game lags quite often even though my windows 8 computer far exceeds the system requirements. That and the fact that the game itself is very slow paced at first makes for an almost unbearable experience. I had very high hopes for this game and I heard many good things but it's just so slow. Sorry. I'm sure it's a great game, but it's just unplayable for me at the moment.
