Corporate-owned wikis have ads and other issues, so fans have decided to go their own way
I think it is somewhat logical as there is literally an entire massive genre of “Japanese RPG.”
There absolutely is something suggesting that: precedent. Though it could be Czech RPGs, Columbian RPGs, Cuban RPGs, or Canadian RPGs. Though Chinese RPGs would be more likely given the game Dev industry there and population.
Also the fact that outside of the tabletop community, nobody calls video game RPGs CRPGs.
The term CRPG is very popular, but it means something different than just RPG video game. Starfield is not a “CRPG” for example. Baldur’s Gate (all of them) are. It’s a conversion of table top RPG style to computers. If it’s supposed to reasonably closely emulate a TTRPG in video game format, it’s a CRPG.
