I know it would sound really stupid if it was true but there isn't anything official to confirm or deny from what I can find.
I know this is only second hand info but the post I read went like this:
Yup, it seems I essentially spent 76 US$ on a new registration code, a tumbler, a map to wipe my glasses with, a security token, a making of-DVD, and an Onion Helmet. The important stuff, that is, the actual game and a 30 days trial, I could have gotten for free, as I actually got a guest pass from a friend. Quote SE support center:
"Regarding your request for account support. Please find your answer below.
Your Buddy Pass account is a full account, if you do not cancel then it will continue billing. You just have an extra registration code now since you purchased the game yourself.
Thank you for contacting the SQUARE ENIX Support Center."
Wow, it would've been nice to know this before I actually ordered the CE. Not that I didn't want the CE, but if I could save 76 $ and still keep the essentials; the game installed and a full account a week before the release of the ordinary retail version, why wouldn't anyone not stinkingly rich go for that instead? Anyways, the box artwork sure is kinda nice....
A previous post in that same thread also mentioned:
From what I remember from FFXI, you didn't need to buy the retail version since you would be paying new monthly charges after the free pass was up. They could have changed it, but I am not 100% sure since SE has changed a few things around lately and hasn't been clear with their communication.
I never played FFXI so I can't verify this - I'm sure someone else can.
I guess we'll find out in a few more weeks what the actual deal is.
In this life you are nothing without someone else to think so.
