Not possible really.
Thing is:
If we look older RPG games and older computer RPG games like: Baldur's Gate or Fallout (1-2) they were really great but need relative deep learning curve.
If we look now best selling "RPG games" like Diablo III, Fallout 4, Elder Scroll V: Skyrim we quite fast see that these games sell because they are really fast to learn, look good and are more of shoot em up / hack & slash and less for deep turn based RPG like Planescape Torment where most of your time went reading things and trying different stuff and "playing roleplay".
If we thing Pillars of Eternity when it arrived I really loved it, still do. But most people are like "what, you seriously pause when fight start and give every order for every party member untill fight is over?" or "are you serious, you read ALL text in the game? Including item descriptions and tomb stones?" or "what do you mean you spend few days just creating your character and reading manual?" if I try to tell them how I play it and why I love it.
Sure it might be interesting to see "Pillars of Eternity V: How to kill a dragon and get level 100 in 2 days" and I bet it would sell huge amount. But would I keep telling people that is "Game of the year, not Witcher III". No. Because sure, it would be fun to play casually. But really roleplaying it, no.
I allso bet that most people who keep telling how great Witcher III is have never played and might not even know that there was a game called Neverwinter Nights and it was used to make Witcher I, good game allso. And real RPG game, really.
