Thanks for the info. I'd be rolling in Japan myself.
Where did you purchase/download, btw?
I'd play on a EU server (as that's where my friends are back home), but I don't want to screw myself over from the start. GMG says it's not available in my region yet... doubt it's coming to these shores any time soon so I'm curious if there's a work-around.
The game looks great, though. Surprised I hadn't heard of it literally until today!
I went straight off the official site since GMG doesn't work here. You might want to do the same if money isn't a problem as it provides the most simple, no-fuss route.
As for coming to Japan, I think that's one of those stay tuned things. But I think that'll be talked about later on.
