I really hope that they use the same Trophy list, I don't want 2 TLOU 100%'s in my list, I don't like multiple copis of the same game in my trophy list.
Also, they better let you import your saves and multiplayer progress over to the PS4 version, I'm not starting over.
God, what to do with these first world problems.
None of the single player data, mutiplayer data, or trophies will transfer over to the PS4. The only thing that will transfer is the DLC that you bought with the season pass (hats, skills, etc.)
Its basically a new start, but experiencing the single player and multiplayer again on the PS4 is something I'm looking forward to. Plus who can be mad about a new platinum?
