Another thing to keep in mind.
For those who now know how to type on a keyboard at 45WPM, do you ever remember seeing someone type fast and think 'I'm never going to be able to do that.'
But by learning how to type letter by letter, instinctually, and your speed gradually improves to the point you're no longer thinking about it.
Soon you're seeing words and automatically typing each letter out to the speed of 20WPM, then 30WPM, and 40WPM or even faster than that.
A controller actually isn't significantly different than a keyboard. Take the PS4 controller for example.
Imagine never holding a controller before.
"Wait, there's an R2 button on the back right?
And the one infront of it is R1?
And there's two of these sticks that go in every direction?
And if you press down on each stick that's also a button? R3?
And there's a center button that I can swipe my finger on? That makes it work?
Why are the buttons on the right named shapes when the rest have letters and numbers?"
Then someone gives you a PS4 controller and pops in RDR2 or Witcher3 and expects you to 'get it.'
Practically every game's tutorial only tells the player new things once, and in too many games the tutorial isn't repayable so the game expects you to have amazing comprehension skills.
And if you have someone there explaining everything... and either over explaining or under explaining... you get the feeling that you need them there to explain it.
A good gaming coach for first-timer gamers can either be a 'training wheels'...
...or a ball & chain.
So, this is why new gamers should be eased into gaming with simple games at first.
Edit - I guess I'm going into much further depth of why I recommended Tetris, then (a racing game), and then (a platformer game) in my first post.
It's a rough draft of what I was thinking, but basically can be summarized as 'Only play the most simple games at first, and as they familiarize themselves with the controller, hand-eye cordination, and the learning curve... gradually increase the complication of the games.
I'm thinking Mario Kart would have been a better recommendation than Wreckfest.
Mario Kart is less complicated, and has multiplayer.
