I've always liked Street Fighter more than Mortal Kombat. With that said, I've had good times with Mortal Kombat, even so. With the exception of Mortal Kombat 4, I have at least touched all of the "old era" MK games, i.e. the original up through Armageddon. For me, Mortal Kombat II was the height of the series. It has been all downhill from there. I didn't even like MK3 as much as MK2. Basically, I agree more with Pat here than with Woolie (though I don't hate MK as much as Pat claims to), mainly because I don't give a flying fuck, yay or nay, if Mortal Kombat is a "viable fighting game."
Of the new ones, though, the only one I've played at all is Mortal Kombat 9 (aka Mortal Kombat with no number or subtitle, which was meant to be a soft reboot of the series, same as the new Mortal Kombat 1 is meant to be, yet again). The main reason I never bothered with MKX or MK11 was due to them being infected with Denuvo, and now, even with that malware ostensibly having been cleansed from them, I still have little interest in buying them. I have, at most, watched Youtube compilations of the story mode movies (the MKX one I watched was done by SBFP themselves back in ye olden days).
It's kind of funny because while I remember Bo Rai Cho (he was the "drunken master" of the MK universe), I have no fucking clue who Hsu Hao was. I mean, I even played Deadly Alliance (and Armageddon) and all, but... ...who?
And man, if Dead or Alive's biggest draw was the "jiggle physics," and Mortal Kombat's biggest draw was all the gratuitous gore, I'd really hate to see the Mortal Kombat equivalent to Dead or Alive's "let's stop bothering with the fighting game veneer and just focus exclusively on the bouncing boobies" thing that was the Xtreme Beach Volleyball games. o_O
(EDIT) Oh, and so many people are talking about how the gore in the new MK games are getting more and more uncomfortably realistic and how some of the devs were allegedly traumatized by all the supposed research they did into real life gore in order to make the new games that way, and I'm over here just thinking "And what, exactly, was wrong with the dozen rib cages and femurs and such flying out of a dude when he got exploded like in the old games?" (/EDIT)
