Well, I've had mine since release day, had no problems whatsoever in setting it all up, everything just seemed to sync straight from my PS3 to the PS4, trophies, FB link, profile settings. I have to say I absolutely love it.
Playing: CoD: Ghosts, BF4 and Assassins Creed: Black Flag.
The DS4 is brilliant, such an improvement over the DS3. The indents in the sticks are a nice touch which immediately feels better than the rounded mushrooms of the DS3, making small movement inputs a breeze which is particularly useful in the shoot-em-ups.
I've synced AC4 with my phone and it works like a charm, though it did scare the B'jeesus outta the missus... I'd left the PS4 on at home and gone to work, was on my break and loaded up the AC4 app on my phone, the missus was unassumingly at home watching her usual crap on TV (Homes under the hammer et'al) when the PS4 took over the TV just to tell her my phone had connected to it!
This led to confusion on the missus' part as she has no clue how to change the "source" on the TV.... On a positive note, she actually got off her a$$ tidied up and made dinner before opting for a nap.
CoD: Ghosts is quite enjoyable, I have only played the single player campaign, I was impressed with the gameplay and obvious graphical showcasing. I may give the multiplayer a whirl over the next week or so. I'm less impressed with Battlefield 4. Though I think this is mainly because I've played all the other BF games on PC so I probably need to give it more of a go before slating it entirely. It just seems a little "alien" on a console.
My bro also purchased a PS4 and when visiting him we sat and had a go of Need for Speed. Looks ok, its no Forza or Gran Turismo obviously, but if you want quick Arcade thrills n spills then I guess its ok. He also showed me a game called "Warframe" briefly, it reminded me of Dynasty Warriors, though with less "mobs" at least the part I saw. I've downloaded it this evening (as its free) and may report more later.
I'm looking forward to Watchdogs ad I'm somewhat dismayed that Dead Rising is currently an XBONE only title. I love zombie survival horror games and to placate my need for this I'm looking into the Dayz Standalone for the PC having played the Dayz mod for quite some time.
Anyhoo, feel free to add me on PSN: Sinful-eye
