I get the impression that it's mainly aimed towards multiplayer games like your CoD, Fortnite, EA Sports' online modes etc. Games where walkthroughs are not really applicable and guides are instead general to the most common situations. Also games - like Smash - where a lot of players default to a certain playstyle no matter what and make common mistakes like hard-commiting to a certain option by default or not taking more subtle aspects of the game into account.
That sounds like a future "What Happened?"... but given all that has been talked about, it's making me uneasy about what such an episode would talk about.
