I chose rating of 4/5 because it is a great console, but I think that at the same price Sony could integrate PS4 camera. Regarding KILLZONE game, I've never been a follower of a game in the third person. I had to get used to because there was not much to be put in the tooth for PACK PS4 at time of release. Yet SONY could do with better PACK PS4 because when it came out, there were still 14 and FIFA ASSASSINS CREED Black Flag. The direct competitor of Sony was much better to offer. I remained faithful to my choice since created the SONY PLAYSTATION consoles.
