When in doubt, go American first.
*smaked in back of head*
"Shut up Jedi and all your Pro-American rhetoric!!"

Just kidding.
No, that sounds JUST LIKE something I'd do, 'cause I've done plenty just like it. I've spent half my life in line at the return counter after getting something I should have checked more carefully to see if it was the right one.
Heck, I bought the Tron game before I even thought to see if it would round a corner in the house to make it into the room I planned to put it in. I was sweating bullets 'til it thankfully made it okay. I dunno what I'd have done if it didn't.
Hey, did you concider if it'd be easier to get your hands on a UK game console and convert the power? I know you had a hard time getting the game, maybe this would be an easier goal than ridding yourself of it and resuming the daugnting task of finding that elusive American one. You think? Depending on how much Gorf means to you. Plus, you'd be able to get ANY game from then on no longer worrying about which nationality of any future game you find.
Think?
