In the rest of world the game has not been released but you can play with a VPN to trick the Japanease server.
There is a second game (a strategy game) called Gundam Diorama Front.
If you are a Gundam's fam you must play at these two games. They can be downloaded for free from bandai/namco server.
I got this set that have a joystick with the lines and colors of a green Zaku and a copy of the game.
I'm using the game on a Imac with Windows 10.
