Information on setting up 3rd account (triple box) using a used 360 ffxi disc

[Ire]

Hmph, thanks for the info and your time Econ. but maybe I have to re word this..

Should have just asked this way,
Hello forum members, hey I am a new player and bought a used copy of FFXI ultimate collection for XBOX 360. Problem is the registration code is invalid/used. Where can I find a new registration code?

I would have answered the same way. Buying a digital PC copy of the game online for the code is the single best way to get the game and every expansion for the cheapest amount of money, and as an added bonus, you get an extra separate code for a hat that helps you level.

Codes are the same between platforms. This means you'll be able to use the code to register an account then use the account on any platform, whether that is the PC, PS2, or even the Xbox 360, and you can log into any platform you have the game installed on.
