A:AnswerYes but you have to open it at home it st because they can't accept a game in new packaging. Also it'll be trade-in value instead of being a new game exchange.
A:AnswerYou don't need to purchase anything except the remote control for the PS4 since the PS3 remote control is not compatible. Unfortunately the PS4 remote control does not have a touch pad or an aux port for headphones (like the dual shock 4 does which allows you to watch things with headphones). If you're used to using a game controller for multimedia input than you won't have to purchase anything additional but I would recommend buying a charging port for the controller so you don't have to fiddle with the cable every time you have to charge it.
A:AnswerBased on the product specs, this PS4 comes with a one year manufacturer warranty. You will have the option to purchase either a 2 year or 4 year Geek Squad Protection plan.
I hope that helps!
