The Witcher3 isn't really an RPG game in my book. Its a <run and gun> Action/Adventure Tell tale game marketed as a next gen RPG. And a VERY good one at that. Nowdays even Diablo (an Hack & Slash action game) is considered an RPG . lol that would gotten a good laugh in the 90s.
I've always found it extremely odd how many people today tend to consider only a very limited definition of "RPG" (at least when it comes to CRPGs, not their tabletop relations/ancestors). These overly narrow concepts generally are restricted to very specific game mechanics, e.g. turn-based combat. Irrespective of the type of game and gameplay mechanics each player may prefer, an "RPG" is simply that - a "role-playing game". To address the quoted example, I was old enough to be around in the '90s, and the developers/marketers (and I, as a player) very much considered Diablo within the RPG genre (
