this is bad... I've started looking some tweet answers by users on the official MagiRecoEn twitter account, and a guy showed a screenshot saying that the game "Won't work if not installed from Play Store". Just like the JP version.
this is utterly stupid. Aniplex first claims this game to be "worldwide, global". Then "nah jk we intended only USA and Canada". Then they don't even know how to handle their servers EVEN when US/Canadian players want to play it.
They even do the stupid region lock thing on the apk itself.
When they get money from ACTUAL worldwide players that use the Apk (Like for FATE GO "Global"), though, they don't seem to be too picky on those money.
I'd like to say a lot of bad words, but this is not the place (and overall, it wouldn't change things). Screw you, Aniplex.
