@bleedingphoenix It gets complicated because I see why they're all classified as "action games".
I think Gaming could potentially have 2 genres for each game.
One describing the gameplay type and one describing the overall tone of the game.

Example is "Black OPS=FPS, action"
whereas "Resident Evil 7=FPS, horror"

But it does get complicated really quickly.
I've heard some people try to claim Mario is an RPG because you're playing in the roll of Mario which is something I definitely disagree with but I kind of see how they ended up with that conclusion.
