Wish I could participate but I wont be around for the NA release of GGXrd. Hopefully a lot of people will give it a try and participate. I messed with the time limited Xrd demo that came out on PS4 awhile back and I can assure you all that it looks amazing and feels great.
For people new to the series check out some of these videos to give you an idea about how the game plays and some of it's new mechanics.
The new RC system
Youtube user Goldenrody has been uploading videos of GGXrd from Japanese streams since it's arcade release in Japan.
Twitch streamer Joniosan streams GGXrd live from Mikado arcade in Japan throughout the week.
Finally, a couple wiki sites that go over character moves and info.
