The director of the game Matt Firor has confirmed that The Elder Scrolls Online will not require a PlayStation Plus subscription for the PlayStation 4. According to the PlayStation Blog where he was talking, Firor told us that the people on the PS4 will have to pay a monthly subscription like those on the PC version of the game. The price will be $15 a month.
Firor has told us that the PlayStation 4 version of the game will run on its own servers and a beta of the game will be coming out before its official release. More information about the beta will be given to us by the studio later on.
