As far as the appeal of fighting games, they are like a game of Chess or Checkers of something like that, only more violent. Unless you're playing against me since I am a notorious poor loser. In which case, fighting games do not seem violent at all. But the judge told me not to play Chess anymore, so I digress.
The problem with fighting games is that you have to be into them, I mean really into them like you find fighting games more appealing than a nice scrotal cuddle to be any good at them and to learn the nuance of play. Fighting games have a learning curve that is like running head first into a slab of concrete and then throwing your body off a cliff. Few have the inclination to work at it enough to actually be any good. Hence why most people just randomly mash buttons on the controller or learn one move and only one move that proves effect, i.e. the throw button, and use that constantly in every single fight.
Now, it could be a balance issue that one move can be so effective that learning other moves is not enticing. It doesn't help that fighting games have these simply moronic and unintuitive "combos" where hitting up, then down, then up again, then down again then the jump button makes your character breathe a enormous fireball on his opponent. I don't know if anyone has bother to figure out the rational for how these seemingly random button presses could have anything to do with the resultant action, but I am sure that it would be moon logic. No, that's an insult to moon logic. Even moon logic isn't that stupid. At least I never heard of anyone who tried to do that with the possible exception of video game web comic writers, the tards.
Incidentally, Mortal Combat vs the DC Universe looks stupid. I predict there will be a lot of copies gathering dust on shelves in gamers' homes within six months, you easily plucked chickens.
Which brings me to my next point, Don't think Yahtzee hate fighting games fans because he doesn't understand the genre. He hates everybody, so stop being such twits.
