I think Runescape once celebrated 200 million accounts created (most of which were bots of course). 5 million is small compared to that.

PC version or the PS4 version? pop in the disc for the installation etc.

It's the PC version, I stated it in my first post :D.

ok, go here and tell me if this was successful. https://preorder.na.finalfantasyxiv.com/na

AAAAAA-123-AAAAAA-123 format needs to be registered there.

Once you have your 20-digit early access code, log in to the Mog Station.

these codes will expire on dec 31 2015

No luck, my copy isn't a preorder though, I bought the retail last month. And this is the site that was directed by the leaflet inside the box to register the game, http://eu.square-enix.com/en/gamereg

After the terrible flop of 1.0 and the flops of almost every non WoW MMO since, well, WoW, it's an incredible success for SE.
Also Naoki Yoshida is awesome and totally deserves this.

I just went to that site, logged in using my alter account, and I get this option. Isn't that the same option you need?

Yes, that's the one, I already did that, and the game is already in my account's "registered games" tab.

check your email for the 20 digit code, and if you haven't yet, pop the disc in already, do it. Don't worry, you only need to use the disc once.

the 20-digit code will grant the bonus pre-order items.

No code was sent to my email, I didn't even recieve a confirmation that a code was sent to my email, and my problem is that my disc is in europe with my mom, so I was asking if is there anyway to play the game without the disc?
