That's fine, just need to be in Japan, or doesn't work with the setting. Unless we alter it for our story.
Something like, Global limited to 1 million copies for first production or something like that to be reasonable. First day simultaneous availability at same time or something. But then, very likely to have lag/ping issues across the game. Lol

Imagine you are in a dual, you think you slash. They can say they dodged, and it was all lag, and there would be nothing wrong with that. LAG OP!
