Amazing game as you'll reading in all reviews, according to all game ranking websites, it's the 19th best reviewed game of all time now concidering how many games have come out, but on release was the 3rd highest rated 360 and PC game ever as they were the launch platforms.
Enthralling storyline constantly challenging your morales and forcing you ro make decisions you may live to regret
Dark story with so much to do in it
The PS3 version as mentioned also has a few new extras in it and the slightly holographic slip case it comes in is great
There actually is no diffrence between this and the 30 quid version.
Great purchase for any next gen console owner
Hope this helped
