In the greatest irony, kiddy games are harder and have more mechanical depth than "mature" games.
>Crash Bandicoot > Dark Souls
>Donkey Kong Country > Metal Gear Solid
>Super Mario Bros (1-3 including Lost Levels) > Bloodborne
>Super Mario 64/Sunshine > Far Cry
>Super Meat Boy > Last of Us

>Team Fortress 2 > Call of Duty
Sony managed to promulgate the idea that their consoles are for a mature audience, and naturally since only kids care about appearing mature, they effectively got a monopoly over the pre-teens market. This is why they can get away with releasing IP's and games with very shallow mechanics that have more flash than substance.

Nintendo, being the actual adults they are and not caring about appearing mature for the sake of it, actually prioritizes good mechanics above all else, appealing to everybody and respecting the skillset of the player regardless of their age. Most broccoli zoomers wouldn't even get past DK Tropical Freeze. Kek. Sony almost cracked the code with Crash Bandicoot but alas Naughty Dog realized they can make much more money with far less effort by just duping kids with guns and edgy voice-acting.

It's no coincidence most highly regarded speedruns are Nintendo games.
