I have just purchased Rock Band 4 for PS4. I have never owned any of the previous games in this console family.
I'm feeling rather constrained by the track list, and would like to add the Rock Band 3 tracks to the mix. I have found information on how to do this.
But the only copies of the game still available are pre-owned. Can the above steps be performed if the game is purchased pre-owned? Can they be done if I only bought the game as of now (as opposed to when the game was released)?
