I have the game on the PS4 and the PC and I primarily play on the PC these days. My nephew, however, has shown an interest in the game. Is it possible for him to play on my PS4 and I use the PC? I tried to create a character on the same server using the PS4 while I was logged into my character on PC and it didn't let me finish. Is it completely not possible or is there something I have to do in order to do it?

Thanks.
