https://chinadigitaltimes.net/chinese/671510.html seems to be the main source. The comments are coming from leaked materials of a CPC-led conference at Beijing International Game Innovation Conference back in September.
http://www.cgigc.com.cn/info/22297.html There's more info on the guidelines on their official website. For whatever reason it's currently not loading (possibly due to increased traffic?), but I'll try uploading the .pdf files of the guidelines to somewhere if anyone knows a good place.

All in all, this really doesn't look good, and doesn't seem to apply to only games - apparently various gay shows and books are affected too. Obviously there are some decent guidelines in there like the banning of imperial japan worship, regulation of gacha/pay to win exploitative 'games', etc. but it shouldn't be at the expense of LGBTQ+ comrades :sicko-no:
I know I sound crazy when I tell people about shit like MK Ultra and other crimes against humanity that the CIA has straight-up admitted to :doomjak:
