It doesn't arrive in my country until next Friday; I've had it on pre-order for a few weeks now.

It's going to be great, I think. Reviews so far have been overwhelmingly positive. I've got a demo that came with last month's Australian PS2 Magazine. Not a playable demo - we haven't had one of those - but a rolling demo comprised of numerous cut-scenes, albeit all in Japanese, with Japanese subtitles. I find it rather amusing to listen to 1960s Russian, British and American Special Forces all chatting to each other in fluent Japanese. Fortunately, the non-English dialogue reduced the number of spoilers from that demo... though it was a pity to see a lot of key characters and events in advance.

I'm greatly looking forward to the full game, though. Apparently the Australasian PAL release has a few bonus features that weren't in the US and Japanese release.
