My PS4 is the first gaming machine I've bought since my Gamecube. Sold that machine years ago. My PS4 is the biggest stress releiver. I love it. There's so much I can do on it along with playing games. The Playstation Live is fun to watch other people streaming games and from their living room. And the DS4 is the best control I've ever used. Love this machine!!
I think it's fantastic. Love the console the controller and now with Outlast (awesome free game) and Tomb Raider, the games are getting better. Can't wait for Thief, Infamous and Dying Light to come out.
I use my ps3 a lot more. NBA2K servers are never functioning (I've never actually been able to even play a game), Killzone servers are small because everyone and their grandmother floods Camp of Duty and BattleCoD 4, Knack is cool but I'm in no rush to beat it due to the drought, and I found the free games that I played, Resogun and Stay Alive, to be crap. All and all I'd kill myself by now if I didn't have ps3
I love it, but I admit to not really playing it. I've only bought Injustice and ACIV for it.
I'm in the middle of doing a translated walkthrough for Yakuza 5, while playing Y's Celceta and Bravely Default, so my 4 is just kinda hanging out until I get Yakuza Ishin in the mail.
