These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Mortal Kombat 9
Ass Pull: Sindel suddenly slaughtering the heroes near the end of the story feels like a rather rushed way to kill off several of the cast members for the sake of the storyline, which made a point about heroes making 'unthinkable sacrifices'.
Awesome Music: Nearly all of the music of the original games gets a remix, including several very well done orchestral remixes.
Kratos. You've got the fans who think he's a great addition to the roster, the fans who are vehemently against his presence in the game, the fans pestering Netherrealm Studios to add a 360 exclusive character, and the fans who just don't care about him being in the game.
With the reveal that the fourth DLC character is Freddy Krueger, the fanbase is further split between those who think he's a welcome addition and those who feel that he's even less fitting in the game than Kratos is and that the reveal is a disappointment after the hype leading up to his release.
Babalities are back in the game. Without Friendships or Animalities to accompany them.
There's also the announcement that goes both ways: Unmasked Sub-Zero, YAYYYYY! Wait, Retro Cyber Sub-Zero, BOOOOOO!
Cyber Sub-Zero is a HUGE one among the fans thanks to being seen as not only unnecessary, but a rather cheap way to change the timeline as well.
Best Known for the Fanservice: Inverted AND averted within Story Mode. Most of the female characters remain clothed to some degree, with one surprising exception at first. No, not Sonya. Or Kitana. Or Jade. Or Mileena. Or even Sheeva. It's Sindel. In what is the only display of "frontal nudity" of any kind in the entire series, when Quan Chi resurrects her to match the events of Mortal Kombat 3, she is brought back naked, with only a view shown of her upper chest above the nipples.
Breather Level: Challenge 150, Gor-Owned, is much easier than anything near it in the Challenge Tower. This is mostly due to the challenge involving you playing as Goro. You keep his ridiculous armor and damage resistance, and you even get a considerable damage boost. Not even the requirement of having to defeat five people without healing makes this at all difficult.
8.8: IGN gave the game a "mere" 8 out of ten, with a one page review and some complaints about the single player mode. The latter falls under sloppy research, since they were that it was too hard, and that the story mode wasn't comprehensive enough. When the reviewer states in the review that when he made remarks about the difficulty to other IGN writers, they noted "Sounds like Mortal Kombat, then" and that none of the other fighting games except for afew feature a story mode.
Some of Goro's and Kintaro's weaknesses can be exploited via these. They can't comprehend uppercut spamming on Normal difficulty, and are also impotent against diving kicks, especially Cyber Sub-Zero's, which is a Godsend when you fight both of them towards the end of Story Mode.
There's also a glitch that lets you do most characters' X-Rays with other characters.
Harsher in Hindsight: The ending to Mortal Kombat: Conquest, where Shao Kahn kills everyone, is oddly prescient of this game, which ends with Shao Kahn killing almost everyone. In both cases, Raiden unwittingly caused the destruction.
He's Just Hiding: A good portion of the fans believe that Liu Kang didn't die when Raiden shocked him, and that he'll be showing up in the next game having made a Face-Heel Turn. Whether or not this is true is unconfirmed.
In addition to the above, three others who some fans believe to still be alive and possibly return in the sequel are Shang Tsung, Noob Saibot, and Shao Kahn. In the case of the first is that Shang Tsung is known to be a death-phobic individual who may have had some sort of contingency plan in place and thus had a back-up body to put his own soul into after Shao Kahn absorbed his souls to empower Sindel. As for the second, Scorpion was also known to have been sucked into a soulnado and survived, thus it wouldn't be impossible for him to have survived as well. As for the last, there are some who believe that he wasn't killed by Raiden and the Elder Gods but merely sentenced to some sort of Phantom Zone like containment. Also in the case of the first two, among those to be revealed to have their souls enslaved by Quan Chi, they were both absent possibly suggesting they are still alive.
Mortal Kombat: Defenders of the Realm gave us a non-canon glimpse of Cyrax and Sektor before they underwent automation; they were respectively shown to be Asian and Black. While we've known that (in canon) Cyrax has been shown to be dark-skinned at the least since his ending in Gold (additionally, his bio for this game confirms that he's Motswana), this game's story shows us all of the major Lin Kuei warriors before they were converted into cyborgs. Sektor is shown to be Asian, thus meaning that he and Cyrax swapped races between the games and the cartoon.
A year before the game was announced, a YouTube user uploaded this video. At the time it was just a show off of Armageddon's "Kreate-A-Fatality" feature, where the player could build their own character, with their own powers, fighting stances, weapons, etc. But now that Freddy was confirmed to be DLC, the video seems (unintentionally) prophetic...
Magnum Opus: With its sheer amount of content, attention to detail, and gameplay that was finally deemed tournament-worthy, it's safe to say that this game has successfully knocked Ultimate Mortal Kombat 3 off of its pedestal as the series' example.
Stryker and Police!Kabal's conversation in the middle of Chapter 12:
Kabal: Stryker, check her [Mileena] out! What do you think? Friend or foe?
Kabal: Dressed like that?
Stryker: Definitely foe.
...And Kano is still frozen.note The last time that Kano is seen in the story mode is when he is frozen by Sub-Zero. Though he likely thawed out of the Ice eventually as Noob Saibot mentions that he received a warning from him about Sub-Zero's defection.
Porting Disaster: Maybe due to insufficient testing to ensure compatibility on a variety of configurations, the PC version may play perfectly to some, while others experience problems like inconsistent framerate - you may play the first round of a fight going with a fast forward button, then the second in slow motion - or sudden framerate drops when some visual effects are played. It can be remedied only by fiddling with some configuration files. Also, the compression of the cutscenes is lower than in the console releases, which causes a jarring contrast with the higher resolutions allowed on PCs; fans have released a higher-res movies pack.
Liu Kang. In the past, he was regularly overshadowed by everyone else. This is changed by having him be more of a chosen one ("He must win" Though Raiden realizes that the message meant something else entirely) and by developing his relation with Raiden by making them become estranged enemies by some of the latter's decisions sometimes having detrimental ramifications.
The Scrappy: Sindel after the events of Chapter 15 where she effortlessly curbstomps 10 people at once killing all but Johnny Cage and Sonya.
It's almost like the story is intentionally making you hate the Elder Gods with the unbridled fury of one thousand white-hot suns to garner a Kick the Son of a Bitch/Rooting for the Empire reaction from Shinnok's inevitable escape from the Netherrealm.
Raiden is now this for the Trope Pantheon runners due to his many What an Idiot moments. Among fans, he's usually treated as just being put through bad writing and still maintains a good deal of popularity.
Special Effects Failure: In the Vita release of this game, there's a bigArt Shift when going from cutscene to gameplay, much more than was noticeable in the home-console version (which was practically seamless). It doesn't help that most shirtless characters look like their muscles are just painted-on now. The PC version also has this problem if your resolution is set higher than the resolution the cutscenes play at.
That One Boss: All the bosses in grand tradition are this, but Shao Kahn regardless of match up is an SNK Boss that will send you crying for mommy.
Challenge #251, you must KO Shao Kahn with Shang Tsung, AFTER facing Baraka and Sindel on maxed out AIs. This is on top of the fact Shang Tsung has a rather mediocre move list.
Challenge #257: Hell, pits you against Noob Saibot with reduced damage taken, damage boosted X3, a super meter that never drops below 2/3, and input-reading AI. Fun times. Fittingly, this challenge is simply called "Hell".
Challenge #269 requires KOing 3 Shao Kahns as Stryker, with no health restore. It practically forces you into a tedious Hit Scan spam.
Challenge #300: You have any choice of chracter, but you must fight all three bosses back-to-back with one health bar as they get bonuses up the wazoo.
Tier-Induced Scrappy: Shang Tsung. He can only morph into to the character being fought, and they can block this to prevent it. His moves aren't that great, one of which even leaves you open for attack, and is easy to do by mistake when throwing combos involving uppercuts. And 2 of his big advantages, his grab and Soul Steal, are useless on the bosses. He can be played okay in the right hands, but even then, he's moderately good at best.
Sheeva as well, considering that for all her power her specials offer, she doesn't have much to work with in combos and specials and is rather large to boot.
Villain Sue: Some feel Quan Chi approaches or outright becomes this thanks to being really important to the villain's schemes and being a Karma Houdini. Subverted as however it helps greatly when it's implied that Shinnok is possibly receiving information from his future self, and thus allowing the two to plan accordingly. Indeed at the very end the two state that everything has gone according to plan.
Raiden just stands and watches the Lin Kuei cyborgs abduct Sub-Zero; that this comes after warning Cyrax against the Cyber Inititave & his saving Smoke from that same fate makes it especially glaring. An argument could be made that his inability to understand his message from the future ("He must win") could fall under this, as he keeps thinking that it means a specific combatant from Earthrealm, even after Liu Kang's victories over Shang Tsung & Shao Kahn didn't ward off Armageddon. In fact, Raiden from the original timeline could fall under this too, because he could have very easily specified who the message "He must win" was referring to, though to be fair, he was just beaten up and about to be killed, so he must have had little time to clairify.
For one, he didn't go to the Elder Gods until the last possible minute, nor explain his visions.
Hey Sonya, Ermac's got a hold of Jax! Want to help Jax out? No? Okay, let's just hope nothing bad happ—Oh wait, there go his arms. Good thing you're here Sonya, now you can stop the bleeding!
Shao Kahn himself at the very start of the game. If he simply killed Raiden there and then as he started hisgloating, the timeline wouldn't have changed and he wouldn't have been annihilated by the Elder Gods.
They Wasted a Perfectly Good Character: Noob Saibot. Not much was done with his character other than what was already known about him in the alpha timeline, and an opportunity to have his rivalry with Scorpion more fleshed out was completely wasted.
The Woobie: You can't help but feel for Raiden after all's said and done. Accidentally betraying your friends, being manipulated by every evil bastard between Outworld and the Netherrealm, watching your world destroyed in an invasion, finding no help from your superiors, and ultimately, figuring out it all went south because you couldn't even understand your own doomed message. Even if he played with the Idiot Ball, Raiden deserves a Friendship by the end of Story Mode.
Liu Kang as well. He is groomed to be the chosen one by Raiden only for the latter's mistakes to screw everyone, including his good friends Kung Lao and Kitana into oblivion. This makes him lose trust in Raiden and ends up getting killed when he fights his mentor out of fury, cursing him with his last breath. Even worse, his arcade ending and Shang Tsung's has him kill Raiden and become a violent thunder god doomed to be killed by Tsung thanks to his annoyance with Raiden. No matter what, Liu Kang and Raiden are doomed to have their friendship ruined.
Cyber Sub-Zero is this both in Story and Arcade Ladder. In both cases he is doomed to A Fate Worse Than Death, both an initial, temporary one, and a second, possibly more permanent one.
Kitana. She feels guilt over failing to kill Liu Kang, which displeases her father, Shao Kahn. She then finds out her life was a big lie and has her mother brought back evil. She ends her life begging her to return to normal before she kills her and dies in Liu Kang's arms and is enslaved by Quan Chi. To top it off, she and Liu Kang are teased to love each other.
Long story short, this game made the setting a Crapsack World. It is utterly heartwrenching to see the domino effect screw over nearly everyone.
