Question On Playing FF14 On A System That Has Only Base Game Registered

[Styrmwyda]

You will be able to play Redmage, but if its level 60 or more, you will not earn experience points on PC until you add the expansion packs for PC version.

You will not have access to the Redmage Job quests as its expansion content.

So you could just login to PS4 and level up and do Job quests, and switch to PC and just play, just remember you can't logout in any area past Heavensward on PS4 and then try to login on PC, it will not allow you to, so logout in a starter city as mentioned above to get around that limitation.

Ok, good to know in case something happens. Usually I log off near my apartment in the Ishgard housing district.
