If I can use the same one as I would for FFXIV then... eh, whatever. Had to make it to register game codes anyway.Fuck, you still need a S-E account? Forget it. Not worth the trouble lol.
Still, I'd just wait on a 50-75% sale. Have my discs including my special light blue disc 1, and I have a PSN version if those are too scratched up, so I don't have much reason to bother on PC unless I can get it for extra cheap.
