I remember when i got my first PS4 on Christmas and got Dragon Age: Inquisition, Minecraft, and GTA V. When i was eager to go multiplayer Ps Plus hit me in the face with its pay 2 play bs. So i have been playing free to play games for 8 months, as my mother did not want to get me a subscription. Yesterday i hopped onto Dragon Age: inquisition, i go to multiplayer and it actually worked, no Ps Plus message came up or anything. I did the same for GTA V and it also worked. I haven't tried Uncharted 4 yet. But i really want to know why this happened.
