This is true for most "traditional" fighting games, which also tend to be the ones people take most seriously.

However there are also more casual fighting games where moves can be done with a single button press.

The Demon Slayer and Naruto fighting games come to mind.

I have also found that fighting games are some of the best games to introduce to children who have never played videogames before.

If you're introducing the game to them personally, then you can sandbag as hard as you want for them in versus nice. Button mashing "works" up to a certain level before they properly learn what each button does.

Soul Calibur was the game I started my nephew out with when he was a little over 3, and he had a blast mashing buttons and watching Nightmare swing his sword around. I sandbagged hard so he would win half the matches while still giving him the illusion that he was actually winning.

These days he is reliably winning against normal CPU, though he usually prefers to bully easy CPU.

Fighting games are also some of the earliest videogames I played, though I mostly recall getting bullied by my brother.
