I’ve heard some people try to use “eastern RPG” instead, but I’m not sure it’s caught on.
For what it’s worth, “western RPG” (or “WRPG”) seems to have caught on; some people call this style “computer RPG” or “CRPG”, but I’d say that even more inaccurate of a label. So yeah, WRPGs and JRPGs.
And meanwhile, we also have action RPGs, which can be subdivided into games that are more similar to something like Diablo (action WRPGs) vs. games that are more similar to something like Ys (action JRPGs).
And then we have strategy RPGs. And then we have MMORPGs. And then we have dungeon crawlers. And then we have roguelikes, which are distinct from dungeon crawlers despite also involving going around a dungeon.
Okay let’s be frank here, “role-playing game” itself was never a great name to begin with in the first place. There’s the famous comment that if you’re playing any Mario game you’re playing the role of Mario. But rather, “RPG” is just the broad umbrella for games that are descended, however distantly it may be, from D&D. Kinda. (I’ve heard that at one point Zelda 1 was called an “RPG”, though obviously the meaning of the term has become a little more specific since then.)
