Well I have playstation 2 and 3 but not gone for playstation 4 due to its price for a common gamer who wanted a experience of 3d gamjng with high quality graphics this playstation 4 is perfect but when it comes to the price this console is a bit costlier as not everyone here in india can afford to have a console of 32000 inr so I would not suggest to use playstation 4 for the common gamers as I am also happg with the playstation 3 it is also having the the quality games god of war etcetra etcetra. For the people who has a lot of money in their wallet can afford playstation 4 but according to gamers like me it wont be suiting. Talking about th specifications this is having great space in hard disk for game storage and high definition graphics uncomparable yo any ither playstation it is the best.
