Wikipedia is written by humans, a.k.a. non-objective people, which is why they call it “duodecimal counting” instead of “dozenal counting” and used to have Talk wars on that page about it. The irrational side won.
If a game has classes like I said before, then it’s a class-playing game, a.k.a. RPG. Something can be a roguelike but not an RPG. Also “roguelike” is a pretty dumb name for a genre and itself causes a lot of problems, but I digress.
