Weird that thread's no longer there on Tieba, but since I don't play the game and can't find any other reference I'll assume it's real. Foreign companies do tend to get the weirdest advice to pass NPPA and they were a lot more strict in order to encourage domestic competition even just a few years ago, like the 'skulls' censorship in blizzard games.

I can say safely though there are plenty of Chinese made NPPA approved games with LGBT representation, just like there are plenty of skulls.
