I've been predominantly an Xbox 360 gamer this current gen even though I own all the systems. I played all 3rd party games on the system and love the controller. Not a big fan of Microsoft's 1st party titles but XBLA has had some great exclusives that I've really enjoyed.
I really can't stand the Dual Shock 3 controller and the PS3 is pretty much my Naughty Dog games and Netflix system.
However, I'm really torn on which system to go for now. Before E3 I would have easily said the Xbox One. But the PS4 is looking to be very attractive given it's £80 cheaper then the Xbox One, more powerful and the Dual Shock 4 looks to be substantially improved. My biggest issue with the DS3 was the lack of handles to grip, loose convex analogue sticks and awful triggers, all which looks to have been fixed. PSN+ is also significantly better value for money then Xbox Gold.
But there's no exclusives I'm really interested in at launch on PS4. The only game I really want at launch is Battlefield 4. But I've played all Battlefield games this gen on Xbox and am really used to the controller. There's also more exclusives I'm interested in on Xbox One like Killer Instinct, Ryse and Dead Rising that I'd probably pick up down the road.
I want to buy two systems at launch to play Battlefield with my wife. So it's hard justifying an extra £160 ($250US) for a controller preference.. as Battlefield is pretty much the only game I need at launch. My wife also refuses to use a Playstation controller even though I've explained the DS4 should be significantly better controller.
Argh so torn.. I know I'll probably own both systems at some point but I can't pick which system (x2) to get at launch for my Battlefield fix.
And don't say PC as it's not an option lol.
