It can't just be me, or maybe I'm biased in thinking things were better back in the day, but I feel like the newer Mario games get easier each new game console that gets released.
Yeah I can get one game taking all of your attention away due to the constant notifications and everything, happened to one of my friends with Pocket Camp. I admit I find Mario Kart Tour fun because some of the courses and game mechanics are unique, but it's not challenging enough to keep me...
I enjoy Mario Kart 64, not because of nostalgia, I was 2 or 3 years old at the time (though I've got a few faint memories of the games) because of how difficult the game is to play with the rubberbanding AI and the weird controller.
