When I was good at FPS games, I used an inverted joystick setup on our old XBOX system that is apparently not available on most modern games. But that was before I had kids. I went for many years without playing video games.
Then when my kids got old enough to play, I started trying to play with them. But I couldn't adapt to not having my old inverted joystick setup. And even when I got sort of OK at it, my kids quickly outclassed me.
So I am done.
