I think this game is similar to the first, but with added extra features, such as the 'freaks' and the renegade orbs. If you liked the first crackdown, you'll LOVE the second... everything that was good from the first game is in the second and has improved! and it looks stunning now!
I have used 3D before, and the HDMI cable I use for my 3D blu-ray player is the same one I use for my PS3, and it works fine. I have updated the article with another possible problem - the fact that the frame rate isn't high enough when you watch a 3D blu-ray which may cause the blurriness. I have tried changing PS3 and T.V. settings, and I have had no luck as of yet on my set up - other people may have found a solution to this problem but I have not.
