> 30 years later Mortal Kombat is the number one fighting game franchise of all time
Smash Bros and Street Fighter are probably more popular actually.
Mortal Kombat really, really sucked between 3 and 7. MK started to get good again around 8, but really it was "Injustice" (which used Mortal Kombat's engine) that made people start taking MK seriously again.
MK9 is a modern, competitive fighter. But its not as well respected as other games: Street Fighter, Tekken, Smash Bros even. Japan has a real arcade scene (or at least, it did before COVID19 struck), so the games that have proven themselves in the public arcades are more fundamentally competitive than American games like MK9 or Killer Instinct.
I dunno how Smash Bros became so popular though.

Honestly, the extreme violence of Mortal Kombat is a big turnoff to the competitive crowd IMO (much like the extreme "sexiness" of Dead or Alive is also a turnoff). Its good for carving out a niche, but... I don't think people actually like seeing the characters they attach themselves to die.

There was a study I saw: its not that violent video games cause violence. Its that violent individuals choose violent video games.
In a mainstream setting, you'll just gross people out with a lot of the Mortal Kombat stuff. I think kids like it (because they like seeing their parents get grossed out). Otherwise, when adults get together to play fighting games... "Injustice" seems to be more popular than Mortal Kombat, despite Mortal Kombat being the mainline game and Injustice the DC-superhero "skin".

Now that I'm an adult, here's my viewpoint on the whole thing. Children like breaking taboos. Adults don't like it when Children break taboos (children should listen to Adults). I feel like Adults sometimes make up stories for why children should listen to them, but this only encourages more taboo-breaking behavior from kids. That's why Mortal Kombat is such a draw for me when I was younger (I knew my parents didn't like it, but that was part of the charm).
Similarly, I see my sister freak out about her daughter playing Mortal Kombat (despite me and my sister playing MK back when we were her age) and turn off the game. My sister claims that the improved graphics make it different... but my eyes see the same thing. Her daughter likes breaking taboos and sometimes not listening to her mom, and playing MK is an avenue to do so.
