I have a Social Club account that is connected to the PS4. I played there for a while. Can I buy a PC key and activate it on the Social Club website? Because there's already the PS4 account. Not that that doesn't work PS4 and PC on a Social Club account.
If you mean that you have the same game status on PC as on PS4 via Social Club connection, then I have to disappoint you, unfortunately, that is not yet possible!
LG and still good luck gaming!
