even, "story difficulty" assumes you know standard gaming conventions taught to gamers via trail and error of the 6-7th generations.

Controlling both the character and the camera in 3rd person adventure games isnt intuitive, its something learned and refined by both devs and gamers from early games like sm64 showing whats possible to games like sm sunshine and sm galaxy refining it. With game like sonic adventure showing what not to do.

Same goes for First person games. We all learned via halo but to a person that doesn't play games it might as well be as foreign as using mouse and keyboard when you only play console. 

heck even going back and forth between the two is jarring and thats coming from someone who played games since the 90s.

A non gamer whos never picked up a controller? good luck.
