Multiple characters at once?

[Jojoya]

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.

He would need to be using a separate service account if you intend to play at the same time.

As for character creation, SE will enable/disable character creation at 20 minute intervals if the current online population for a world gets too high. If it tells you the character cannot be created on the selected world at that time, save the appearance data and wait a little while before trying again.

The game will kick out one of you if you both try logging into the same account.

Also, I'm not sure but I think if you have a PS4 account you can't use that to log in to the PC version? SOMEONE PLEASE TELL ME I'M WRONG!

As SnowVix said, it's possible to attach PS license to a service account that already has a Steam or PC license. That way you can use either platform to play your character.

What players can't do is attach a PC license to a service account with a Steam license or vice versa.
