Who seen the past era of rpgs are clearly in mind what rpgs are and not.
Language evolves and the trick is to keep up with it. To "those who seen a past era", a clue was a ball of yarn. To those living in the current era, it meas a hint leading to something. A bundle of sticks used to have a different term, and cigarettes are still called something else in the UK. If I were to use that term in the USA, I'd get my lights knocked out.
Language evolves especially rapidly in new-fangled fields like tech and gaming. Used to be RPG was a Dungeons and Dragons thing, now Witcher 3 is an RPG. It's great you feel strongly enough about your elder definitions, but you're going to have more and more trouble keeping up with how the rest of the population perceives "RPG". I can guarantee at least 80% of people thought Witcher 3 was a roleplaying game (though I can see why others would argue why it's not.)
If the police ask me for a clue and I throw them a ball of yarn, they're not going to understand. If CP77 releases and you claim it's not an RPG, then people aren't going to understand. We're just going to have to adapt.
And yes don't tell me the term RPG is vague.
It is in 2020 though. Has been for some time in fact.
Again, I respect you think differently though. It's important to have someone around to remind us of days gone by and how we got here. At the very least, we can't really blame marketing for juggling these evolving terms (which is what started this debate), if it is accurate to how the rest of the market sees it. (Or was it marketing that started the deviation?). Still, you're inevitably going to be the old guy in his rocking chair, shouting at the kids to stay off your lawn and how they missuse "RPG" - both with very little result. They're just going to "Okay Boomer" you.
We might be going off topic now though...
