To play network PS4 it is mandatory to have the Playstation Plus, and in the pack I took a 3-month subscription was included. In addition to network games membership provides access to PSN every month to 2 free games on PS Vita, 2 free games on PS3 and PS4 2 free games, and if you look over one year it is worth the cost. (That's my opinion after everyone does not think like me, to you)
