Ok so, my friend has a PS4, but she wants to get final fantasy xiv for the ps4. Now there's a sale going on in the ps store for the digital version of the game and it's 12$ for the normal game and 22$ for the collectors. But here's the trigger, she only has a ps4 and not a ps3. So if she were to buy the game off the playstation store via the internet, it becomes attached to her account, is it possible then to upgrade via the mog station, if she creates a account before hand and links it to her PSN? Or do you NEED a ps3?
