This bothers me. I lost my linked PSN account. Unfortunately, ticket after ticket won't let me recover it. I've made peace with that. Luckily, I also have an Xbox. Now I don't care. Good job messing that up. Now, two subscriptions are required to play on the Xbox unless you're on the Free Trial...

You really messed up on this one. I wouldn't be surprised if this is discontinued after a time.
I think this was the same case when they had FFXI on the 360. You had to have XBL Gold on top of the FFXI sub in order to play it on that console
