It has been revealed that you don’t need a PlayStation Plus subscription to play Final Fantasy XIV: A Realm Reborn on PS4.
PS4 games usually require a PlayStation Plus subscription for you to play online. There are a few exceptions and it looks like Final Fantasy XIV: A Realm Reborn is one of them. You only need to pay for the game’s own monthly fee to play the game and nothing else.
You can also use a keyboard and mouse to play the game on your PS4 if you want to. The touchpad on the DUALSHOCK 4 controller can also be used to navigate through the game.
Final Fantasy XIV: A Realm Reborn on PS4 is due out in April 2014.
