I'll add all you guys' PSN id's/everything, but I did a little reading online and apparently MGO is region locked.

Like I've said, I really like MGO alot, and it's a blessing that Konami was actually able to make a good online experience of MGS, especially after what I feel was not that good at all in MGS3, but their handling of the online system was atrocious. I mean, you need 4 ID's to play in the championships: PSN ID, Konami ID, Game ID, and a gamebattles.com login. Damn.
