Yeah contact your sellers. If you're lucky you can get a good amount of people to cancel. I was in this same situation, I wanted to buy a new case/cover for my PSP. I didn't want it anymore. I told the buyer, they said "Okay, but I don't know how to cancel. Just leave it" Ebay then automatically kept on sending me "Buyer wants you to pay". When I told Ebay that they agreed to let it go, they cancelled it and told me when you commit you have to buy. Just talk to the sellers and send a message to Ebay about the glitch.
Edit: I still don't know why you went to Ebay for Final Fantasy XII, I think you might be able to find the greatest hits at Best Buy or something still. Plus the used game section of any game store will have it.
