In board gaming, there are fairly clear "families" of game which are broken down by a combination of mechanics, play style and audience. We might talk about "party games" for instance, and there are groups that rejoice in names like "point salad", "waro", and "block games".
These won't mean anything to do you if you don't play board games, and that's fine. I'm just trying to get across the idea that people in that scene like to draw relationships between titles that are distinct from just "fantasy", "sci-fi", "superhero" or some other thematic label.
My question is: are there any similarly accepted labels for game groups when it comes to role-playing? It seems there is for particular kinds of indie game like "one-shot" or "world building". But within the vast bulk of moderately complex, campaign-focused games that are the cornerstone of the hobby, are there any widely understood "families" that gamers refer to?
I am particularly interested in how such "families" might be used to introduce new players to the world of role-playing, so have tagged this as such.
