Really? eh might be because Its one of the genres I follow so I got used to using that abbreviation. Most games containing netorase content I've seen people use that abbreviation. Threads from a certain pirate site, steam curator pages, some Itch collections and some games here use that as a tag, some steam and reddit discussions used the abbreviation. I guess I got used to using it since Its a genre I follow I thought it was a known abbreviation.
