I was going to get the 360 version, but it is in fact blocked off from the PS2/PC versions. Part of me getting this game is to play games again with my local friends who have gone around the world to university, and they don't have 360s. It was a tough decision, because the 360 version was more appealing to me (Voice chat, also links with Japan 360 version), but in the end I'd get to play with more people I actually know, also from these forums.
