No unfortunately you cant... I remember buying ESO and being confused as to why it doesnt work, turns out that you must have PS+ in order to play online with other players (ff14 is an exception but not comparable to ESO, plus you must pay monthly to play the game)... if you want to buy it, buy it for a whole year, because like that you get a discount.
