Wife wants to join as well qustion

Hi all, its been a few years but got back in to the game on xbox 360. Now the wife use to play as well but quite and she see's the new stuff going on and likes it. She wants to join but also play on xbox, I have 2 copys of ffxi xbox but only go the one code witch I used. Can I buy a code online some where and use the second disk for her system. Thanks

Codes are only region-specific, not platform-specific. As long as you have install discs for all the expansions you want to use, you can use any account to log in. Buy the game for PC, like on Steam, and make her SquareEnix account. Then just log in on the Xbox and play.
