Hey, so a friend of mine has the game on PS3 and I got it on PS4, and we really want to play together. Now I know that wont work, so I am thinking of getting the game on PS3 so we can. But I am wondering, If I get it on PS3 is there any way for me to keep my characters, and then also, at any time, come back to PS4 and have all the progress from the PS3 saved on the characters? or do I have to start fresh on the PS3 entierly? Thanks for any help guys!
