Some stuff I really hope they get right in MKX:
1. Lighting. It annoys the crap out of me that some effects that should cast light don't, while some effects that should not cast light, actually do. Raiden's hands' lighting during his victory poses should be blinding in a way that should make everything else black. I mean, he has a 40cm electric arc between his hands!!! Well, the game doesn't think that should emit light apparently. Stuff that does emit light however: Sub-zero's ice, which I remind you people, is supposed to be ICE!, and Rain's water specials, which are meant to be WATER, damnit! While they're at it, please lower the average lighting level in the stages. Most of them are full-blown lit. Where's the mystique in that?
2. Cheesiness vs badassery. If characters in MK1/2 were a mastiff that looks at you silently knowing he can murder you whenever it wants, in MK9 they are like rabid poodles that need to be as obnoxiously loud and noisy as they can manage. I got the first hint of this in the first trailer, when Raiden faces Shao Kahn. Everything was right until Raiden opens his mouth and lets out this "BLAAAARGH!" before charging at SK. It seems like no special can go without some babble scream. THERE'S NO NEED FOR IT!
Also, don't get me started on the round start crap quotes. What's with the teenager-ish bluffing? You're supposed to be the universe's top elite of fighters for christ's sake! Who writes this crap? Also, some of the victory animations and specials... The one most affected is Raiden. What's with him shooting those two random bolts into the air at the start of the round? Also, couldn't they have made them feel more underpowered with that "chirp, chirp" sound? Same thing goes to his bolt power. In MK1 it looked like this tangled lighting which made this satisfying blast sound and visual effect when it hit. In MK9 it's this indistinct blue light as it was in MK4, which makes this "schweef" sound and does almost nothing when it hits. Also, the last hit in Raiden's X-ray, that ball that sits in his hand, which he puts in front of the opponent's face and "pfffst!" I mean, REALLY?
Also, over the top stupid fatalities. A couple that come to mind are Johnny Cage stuffing that award trophy into the other guy's neck, and Kano punching a hole in the other guy's chest and stuffing his head into it. What is this now? Happy Tree Friends?
3. Model anatomy and portraits design. I don't think I need to delve into detail on this one. The models look RIDICULOUS, and so do the portraits. If you can't manage a proper human being, hire people to do 3D capture and be done with it. About the portraits, most of them are laughably bad, looking like their faces are all crooked and asymmetrical. Do they even have an art QA dept that check the stuff?
4. Music. Does anyone recall any of the songs from MK9? Because I sure do remember all of the ones from MK1, 2 and 3.
