What was I thinking?
I was thinking I didn't want to have to wait another six months to get my hands on this game, and seeing as how there's no real difference between the US and UK version it seemed the best thing to do. I didn't know Wi-Fi was going to be needed for all the extras/sidequests, just for the extra dungeon, and I'd heard differing stories about that. Some saying it was needed, some that it was'nt.
What I'm going to have to do is just play the main game for now, then when the PAL version is released buy that and sell this one. Or maybe buy a cheat card that can unlock the extra features, if that's possible.
