Thank you chobit_A5HL3Y and I really appreciate your help.
Two more things, I have noticed that I created Square Enix Account with not a perfect name.
I have registered my FFXIV game inside my Square Enix Membership.
1. If I create a new Square Enix Account but there is no FFXIV game registered in Square Enix Membership, can I play FFXIV game or I must have FFXIV registered in the same account to play FFXIV?
2. My PSN Account is US region and my FFXIV is EU region, so I have create a new PSN Account EU region for only 1 game (FFXIV). However, all my trophies are in US region. So can I buy a redeem code of US for FFXIV EU region (PAL) and will it work? (even if i start from Zero)
I have 2 PSN accounts right now: A) USA Account: with all my games + trophies B) Europe Account (Created yesterday): with only 1 game (PAL FFXIV)
Besides I have 1 Square Enix account: I) Square Enix account: In the Square Enix Membership, FFXIV is registerd.
I wanna do this (if it is possiable): - Buy Redeem Code of USA region - Put it in (A) USA account - Create new Square Enix account eg. (II) - Play in USA Account with new Square Enix Account
Because everytime I open FFXIV on USA account, it asked me for redeem code. Q1: Can EU FFXIV with USA redeem code works? or I need to buy a new US FFXIV (game+code)?
PS. The new Square Enix account (II) will be without FFXIV in the membership as I have already registered it in (I) membership). Q2: Thus, does FFXIV requires the game FFXIV to be registed in same Square Enix account of login?
