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: Final Fantasy X
Angst? What Angst?: Tidus is surprisingly friendly and good natured for a teenager who was emotionally abused as a kid, lost his mother (by implied suicide), had his town destroyed by Sin and got transported to another world with no way back. It gets even more surprising near the climax when he learns that he is not real and states that he is happy nevertheless. He does show angst at some moments but he remains in a good mood.
Anticlimax Boss: So you've finally defeated Jecht in a boss battle that was both emotionally cathartic for Tidus and extremely epic for the player. Now you turn your attention to Yu Yevon, The Man Behind the Man and true Big Bad, who turned Jecht into Sin in the first place and dragged Spira into an endless death cycle for centuries. You confront him for the final showdown, and he's... a giant tick. And completely harmless, thanks to perma-Auto Life. Not quite what you were expecting, eh?
The final fight against Seymour is disproportionately easy compared to what came before him. To put it in perspective, Yunalesca had a combined total of 192,000 HP. Overdrive Sin was a Timed Mission boss with 140,000. Seymour Omnis has 80,000. He's also far more manageable than even his previous boss fights, not using status effects, flunkies and only using one element unless you actually make him. It's almost as if this fight was an afterthought, with most of the effort and budget going towards making Jecht AWESOME.
Anvilicious: The scene where Wakka discovers Rikku is an Al Bhed, and the subsequent cutscene consists of Rikku protesting the way people of Spira follow Yevon, demolishing the Strawman Religion with such points as thinking for yourself instead of following blindly, and asking for proof that Yevon's teachings are the right way.
This game itself is a bit of a Base Breaker in the Final Fantasy fandom. Some hate it for it's narmier moments and wangsty protagonst, others love it for Narm Charm or interesting characters and story building.
This was merely fans jumping to conclusions about the implications of the audio drama entitled Will that was included with the Final Fantasy X HD remaster. Shinji Hashimoto (one of the senior producers of the series) has gone on record stating that this was meant to be nothing more than an entertaining bonus feature and have no plans to continue the series further. This has of course led to the argument (particularly among shippers angry that it breaks up Tidus and Yuna) as to it's canon.
Some VERY vocal gamers tend to dislike the HD Remaster soundtrack, while other think it's a lot better than the original. It doesn't help that said original soundtrack is officially one of the best-selling of all time. You will be hard pressed to find a concensus among the players on which OST is better, since the quality of the remastered songs vary greatly, with some sounding better for ones and worse for the others. It really depends on the track.
Deconstruction Fic: Quite a few, about how much it would hurt to accompany your surrogate baby sister to her inevitable death, which everyone (including her) wants to happen. In the sequel, fics about Yuna hiding her pain.
Draco in Leather Pants: Jecht was a Jerkass and emotionally abused his son. He got much better, true, but many fans like to set him as the pinnacle of manliness or proclaim he was a good dad and it was Tidus's fault for not appreciating him.
Jecht's wife tends to be treated to a bit of this by those who outright hate Jecht- she's the longsuffering wife who tries her best to be a good mother. The game implies anything but, as she's portrayed as completely obsessed with Jecht, and being so neglectful of her son that Jecht has to call her out on it. Let's face it, Tidus turned out extremely well for a child who was subjected to both emotional abuse and child neglect from both his parents.
Auron is one of the most prominent Final Fantasy examples, a Stoic Woobie oozing Badass in every moment of screentime he gets. As often happens with this franchise, fans are split over if the game and individual characters are good, bad, or in-between, but pretty much everyone agrees on how awesome Auron is. Even Spoony, who hated this game with a fiery passion, loved him.
Jecht's got quite the following as well. He's so Badass and cool, some actually even overlook his Jerkass tendencies simply because of how much they can't stand Tidus. He got even more popular after Dissidia: Final Fantasy, becoming a manlier-than-manly Memetic Badass thanks to his portrayal.
Rikku also deserves special mention, having earned herself Viewer's Choice awards from G4, as well as awards for her voice actress, Tara Strong.
Fan-Preferred Couple: Auron + Lulu is practically a cottage industry. Cold, aloof personalities in need of some happiness (or at the very least a hug)? "It practically writes itself!"
Another one popular is Tidus and Rikku. The two are cheerful, work together several times in the game and there are some times in which Rikku hugs Tidus in comical fashion.
"Funny Aneurysm" Moment: Playing through the game a second time and knowing that Yuna's pilgrimage will end with her sacrifice changes your perception of many early scenes. Especially leaving Besaid.
And anytime that Tidus mentions to Yuna what she should do after she defeats Sin. Interestingly enough, flashbacks show us that Jecht did the exact same thing with Braska. Both Yuna and her father just smile in response.
Game Breaker: So many! On your first time through the game, it's recommended that you fight the last boss as soon as it's available. If you go and start doing sidequests first, you'll pick up a few Game Breakers and the end will be disappointingly easy.
Yuna's celestial weapon Nirvana turns her into a death machine. It breaks her damage limit and lets her cast any spell for just 1 mana— including Holy, which normally costs 85. Even better, once Lulu gets Ultima and Doublecast, Yuna can immediately learn both with a black magic sphere and a special sphere. Yuna can then doublecast Ultima, doing tens of thousands in damage to all enemies, for twice the mana than the weakest Cure spell.
Getting the Nirvana, as well as levelling it up the first time (while it would still be useless then, it would allow Valefor to break the damage limit), can be easily accomplished well before a certain That One Boss.
Quick Hit allows you to attack, and then get a second turn with almost no delay. Keep using the ability and your enemy takes forever to get an action. Many videos showing people fighting optional bosses show them spamming Quick Hit over and over.
Wakka's Attack Reels Overdrive + World Champion + high Strength = 12 max-damage hits, for a total of 1199988 points. All but the toughest Bonus Bosses die in one attack. Getting it is a ridiculously long process, but once he has it, you might as well just have everyone else Entrust their Overdrive to him.
Mindy's Passado can do fifteen max-damage hits if Yuna's strength is high enough. While this is definitely more net damage than the aforementioned Attack Reels, it's somewhat less reliable due to the Magus Sisters' pseudo-random AI, meaning that while you can influence Mindy to use Passado, you can never outright guarantee it like you can with Attack Reels. In the end, which you prefer comes down to risk vs. reward.
Also, Passado's individual hits may be lessened by armor, which becomes very noticeable against tougher enemies.
Yojimbo is a summoned Aeon who fights for money. He's supposed to act randomly depending on how much you pay him. If you play your cards right you can guarantee he will use his ultra-rare "Zanmato" attack, which kills literally anything in one hit, even if its immune to instant death.
Yojimbo can do an extraordinary amount per turn for just 10 gil.
Hell, any Aeon at any point can be game breaking. Many people who have played the game before avoid using them just because they make the game so easy.
Or they build up their overdrives and then try to keep them for when they really need them, ending up never using them again.
Rikku's "Mix" Overdrive, so much so that most guides for the Dark Aeons/other high-level bosses make a huge deal of using it. The best combination is Final Elixir, which heals the entire party to max HP and MP, revives K Od party members, and cures all negative status effects. Other awesome combinations include Trio of 9999 (every attack does 9999 damage), Freedom X (the whole party can cast spells for free), Hyper Mighty G (casts Shell, Protect, Haste, Regen and Auto-Life on the party), and many, many others. Rikku becomes very useful in many self imposed challenges, especially when she fulfills an effect equivalent to what you have decided not to use.
There are entire guides revolving around eschewing summons, instead using Rikku.
For Blitzball, the Jecht Shot. With very little strategy and enough HP to use it constantly, it can result in almost effortless victories.
There's also a glitch in the Blitzball enemy AI: As soon as you have the lead, have one of your guys holding the ball swim into your own goal. The opposing team has no programming for what to do and will swim uselessly around in circles until the time runs out.
Nap Shot. If it hits the goalie, it has a chance of knocking them asleep. Sleeping goalie = Goal every time you use the "Shoot" command. Combine with the Jecht Shot and double-digit victories become trivial.
The ability to make custom items with rare items can be game breaking. Buy a few sets of equips: one should be Fire Eater, Water Eater, Zombieproof (Yuna's should be Deathproof), and Stoneproof. Yunalesca? Bah, her fancy status effects do nothing. You can't be turned to stone either (making one of the bosses that gives you trouble when getting Anima a cakewalk). And you can shrug off most of the foes that hit all creatures with elemental attacks. This doesn't exclude much besides custom monster bosses.
Later on, you can snag customizations like Auto-Haste (Haste for as long as the user has the armor equipped), Auto-Phoenix (user will get a free turn to automatically use a Phoenix Down if another character is KO'd), Auto-Protect, and Auto-Shell (the latter two effectively doubling your Defense and Magic Defense, respectively). Not only are they ball-bustingly beneficial, they're essential for tackling the Monster Arena bosses. The ONLY catch is finding out what items give the benefits, who has them, and how much you'll have to bribe them to get what you need.
Germans Love David Hasselhoff: In Japan, Jecht is just another tragic villain, but he has a pretty sizable fan base in the West. It's mainly because of his oozing testosterone and being a rare Final Fantasy lead who happens to be middle-aged. Might also help help that he's got a genuinely good English performance.
Goddamned Bats: The Chocobo racing minigame has birds that exist for no other reason than to eat away at your time as they attack in an inexplicable rabid frenzy.
Harsher in Hindsight: Similar to "Funny Aneurysm" Moment, many scenes involving Yuna's pilgrimage involve this. One shining example is when Yuna protests Luzzu going off to Operation Mi'ihen, in which he, depending on your choices, can get killed, and Auron tells her that Luzzu has made his choice just like she did when she became a summoner. Considering that Yuna will die in the Final Summoning if she doesn't on her pilgrimage, this becomes quite a bit harsher.
With Auron, it's not memetic. He really is just that badass.
Mis-blamed: An odd inverse Type 2 in regards to the voice acting—a lack of Executive Meddling when it would have been beneficial. Many of the flaws stem from the actors running on their own ideas and concerns (James Arnold Taylor starting Tidus off with his whiny tone, John Dimaggio inventing Wakka's accent, and Hedy Buress trying to match the animation's lip flaps with her weird pacing). But isn't it the job of the voice director to worry about things like this, or at least to try and keep the actors' ideas consistent with each others?
The laughter scene is a Type 3. It's commonly cited as an example of bad voice acting, but it's invariably taken out of context - Tidus and Yuna are intentionally trying to sound as fake as possible. Not only do the characters sound just as broad and over the top in the Japanese version, within less than a minute of that laughing scene, the rest of the characters take a look at them and say "We thought you guys might have gone crazy."
Self-Imposed Challenge: There are varying levels of this, including no summoning, no overdrives, no sphere grid, and starting equipment. ThisGameFAQs guide takes the trope to its logical conclusion, explaining how to complete the game without the sphere grid, summoning, equipment customization, overdrives, running away from battle, the "No Encounters" auto-ability, or the rare items you get from playing blitzball.
Malboro's Bad Breath. Its status effects include poison, darkness, and berserk or confusion; an easy ticket to an unavoidable Game Over. Even worse with Greater Malboro, as in some areas it will always ambush the party and start with this attack. To add insult to injury, neither one will ever use Bad Breath on aeons (who are all immune to most status effects), resorting to regular attacks instead.
Sin's Giga-Graviton. It's an instant Game Over. Not an exaggeration, as the cutscene of the blast blowing up the airship indicates.
That One Boss: There likely isn't a single player that didn't lose to Yunalesca on their first attempt (unless they read a guide). The second and third forms of Seymour are no picnic either.
Going into details with Yunalesca's difficulty: Her first two forms aren't that bad. She'll use an attack called Hellbiter starting in her second form that does a small amount of damage and inflicts zombie status on the whole party, and then most of the damage she does comes from her using healing spells on them, which she will keep doing if even you remove the zombie status, because she's always follows a set pattern. The bad part is her third form, where she starts using an instant death spell on the whole party, which you can only survive if you're a zombie (and thus can't be healed) or have rare (at that point) Death Ward or Deathproof armor.
Evrae and Sinspawn Gui are also a pain.
Evrae is particularly obnoxious because if you have, up until that point, been depending largely on Yuna's Aeons to get you through tough battles instead of properly training the rest of your team (something that many first-time players are prone to do), you're going to run into a lot of trouble when those Aeons are not available.
It's not just the lack of Aeons that are the problem: Yuna is your team healer as well, and despite Rikku now having what is likely a small mountain of Al Bhed Potions (which heal the party for a thousand hit points and cure a small gamut of status effects) so she can act as a de facto White Mage in place of her, it is really hard for her to keep up with Evrae's damage output.
You say you want Lulu's ultimate weapon? Be prepared to dodge 200 lightning bolts in one sitting.
Tip: You can pause without affecting the counter. Do it in batches of 10 or so with pauses to rest—then it's just tedious instead of hair-tearingly frustrating.
There's also a sequence (glich? Exploit?) in one section of the Thunder Plains that makes it far easier. There's a little crater right next to one of the towers, and if you walk from the tower and press X as soon as you touch the edge of the crater, you automatically dodge a bolt even if there was no indication one was coming. Then walk back to the tower and repeat. Note: if you don't have No Encounters, you may screw up the timing due to a surprise fight.
Which is nothing compared to the amount of time you'll need to be prepared to waste to get Wakka's ultimate weapon. You must play a minimum of 26 games of Blitzball with each match about 20 minutes or so (a tournament, a league, a tournament, and a league). Also, since league prizes get set at the end of the last league game (before you can unlock the necessary prizes in a tournament), you'll have to play 20 more games to clear out the deadwood if you don't want to just reset all Blitzball. That's about 8-15 hours of play.
The butterfly minigame. That damned butterfly minigame. You need to catch every blue butterfly in 40 seconds. Touching a red butterfly will cost you 2 seconds and force you into a battle that you cannot escape. Any enemy encountered during the minigame is twice as tough to defeat.
To get the sigil for Kimahri's ultimate weapon, you need to complete the same minigame in 30 seconds.
Getting the sigil for Tidus' ultimate weapon will more than likely have you either swearing, speaking gibberish, or throwing your controller as you try to get a time of less than zero on the chocobo race.
Or, if like some players, you manage to get the 0.0 score on your first race (stick to the left, it makes it quite easy)...but then realize you have to do it again because you can only get it as a prize from the second race onwards, since she doesn't actually start keeping score until race 2.
They Just Didn't Care: This is starting to become a bit of the sentiment towards the HD edition (at least, in regards to the actual HD graphics). The backgrounds and FMVs look fine, fantastic even. But the regular cutscenes have managed to create worse lipsync than even the original version had due to the new faces. In addition, while the girls (save Yuna) generally look fine, the male party members' (save Auron) new face models come across as akin to rubber masks, with the common citing being Tidus having an overly round face now, and Wakka having a creepy Cheshire Cat-like grin whenever he speaks. There's also the fact that the majority of NPCs still use their original face models, so seeing a party member standing next to them in a conversation can be rather jarring. However, this mostly only applies to X, as X-2 had higher quality models to begin with and thus didn't see the need for redone faces. In the end though, Square can't really take too much blame, as the HD remastering process wasn't done in-house (like Kingdom Hearts HD Re MIX), but rather, outsourced to a Chinese company.
For audiophiles, the new remastered audio has also been a sticking point. The remaster soundtrack has mostly been considered a success but the Audio has a tendency of losing it's Dolby Digital Surround Sound every time the game cuts to a FMV Cutscene. It's Kingdom Hearts Remaster counterpart did not have this issue.
Too Cool to Live: Auron. Technically, more of a "too cool to be alive when the game starts in the first place." Surprisingly, he was more expressive when he was alive meaning he become cool when dying.
Jecht oh so much in technically speaking since you know he's sin in the same regard
Huge subversion with Yuna. She's meant to die at the end of her quest, and yet she ends up living to break the cycle of Sin for good. She was Too Cool To Die!
Values Dissonance: The entire Tidus/Jecht relationship, which goes a long way towards why fans in the US and Japan think differently about our main character. In Japan, hating your father is a huge deal, because of how much importance is placed on family ties in what is a heavily Confucian-influenced society (which places loyalty to one's family above all). In the US, it's seen as just someone with "daddy issues".
Also, Tidus's childhood abuse. While obviously neither side supports it, in Japan people are told to "stay out of it" when finding evidence of such things, and as a result a lot of children suffer in what has been found to be an epidemic problem in the country. This probably made Tidus's character a lot more relatable to Japanese players.
Villain Decay: After defeating Seymour for the second time, he drops out of significance in the plot and eventually becomes a complete joke. Not even the main characters take him seriously anymore, with Tidus' reaction to their final confrontation being one of simple annoyance.
Ironically, he becomes tougher as a boss, so I guess it all balances out?
Even the battle music seems to support this. The first fight against him uses music that is creepy and ominous. By the fourth and the final battle against him, the music is an upbeat and cheerful Disco/Techno beat.
Visual Effects of Awesome: The art direction's beauty still holds up long after PS2 graphics become outdated. Just imagine how it'll look in HD...
What Do You Mean, It's Not Symbolic?: Right before Yunalesca, you see the past form of Auron fall to his knees in despair. If you take notice, he puts himself into the pose used for a person committing seppuku. When the current Auron stands behind him with his sword (acting the part of the kaishakunin, or second person in the ritual) and slashes through his younger self's head, he is in a sense killing off his past and what he saw as his greatest failure.
