I think they have a bit more because they have classes, but I was going to go there next. Also, the action RPGs are often pretty hard to distinguish from games like the Batman games, AC Odessey, Horizon: Zero Dawn, and so on. Immersive sims are another genre hard to push out from under the RPG umbrella.ARPGs can do that too. I would say that something like Titan Quest or Torchlight for example don't include any other points than the first either.
Like @VillainousVelKoz said, it's a bit of a spectrum. What's more, the target isn't something like 480nm, it's more like "sorta bluish," so there are lots of turquoise and blue'ish violet games to wonder about.
No worries about disrespect - I'm trying to oust the whole "RPG" term. At least you're limiting your destruction to just one subgenre.Yeah, no disrespect to JRPGs—they're not my favourite but I've played a few in my time—but I don't consider them to be RPGs and I don't think that opinion is very controversial. That doesn't make them bad, it just makes them a different thing.
I'm not so sure about that history. They have, shall we say, common ancestors. There's a reason why the Final Fantasy games have an "Ultima" spell. But they did follow a very different path - one dominated by consoles instead of PCs.As you say, it's true genealogically too, as well as mechanically. RPGs as we use the term come from Western tabletop RPGs like D&D. Those tabletop RPGs are all about that open choice-led experience. JRPGs have a different genealogy that doesn't include that kind of free-wheeling dungeonmaster-led experience.
You WILL see a lot of choice, though, it's just not in the narrative or character appearance. I think the variety in skills & spells the materia options in FF7 give you easily rival the skills & spells you can pick from in Baldur's Gate, and you aren't stuck with your choices in FF7. FF10's skill tree is very complex, and pretty huge as well.
