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.
Anti-Climax Boss: If you prioritise story progression over character development, then the final boss fight can be Very Hard. If you end up with a high-level party because you've been on a long Fragment hunt or something ... not so much.
The existence of this game in general, considering the mixed reactions that the first game received, and the fact that the wait for Final Fantasy XV is becoming longer and longer as Square spends more and more time on sequels, spin-offs, and DLC.
The relative lack of Sazh and Snow in the main campaign has frustrated many fans. Both characters eventually received DLC scenarios.
And now that we are at it the DLC weren't that well received most notably the true ending chapter. Even Word of God admitted this resulting in the sequel having only cosmetic changes as DLC.
Many fans aren't too happy about the Monster System or the whole "Serah and Noel are the only controllable characters." Even less people are happy about Lightning having less than 30 minutes of cutscenes and only being playable for 10 minutes when Square Enix put her on the front cover, 40% of the back cover, is present on a dozen pages of the manual, the soundtrack, the first trailer was all about her, promoted her as the main protagonist for the first six months after XIII-2's reveal, she's been present in all of the trailers, has an action figure, was hyped as having Caius as her "fated rival", etc. Yeah... great job there, Square.
The ending of the game is quite a Downer Ending, and also rather confusing, causing the fandom to split between hating the game for its ending or defending it for other merits and saying those who think it's bad "don't get it".
The game being overall made much easier than its prequel and the exact same battle system. Fact that the game is so easy results in several of the roles that were helpful to the point of being absolutely necessary to win Boss Battles to be pointless since you'll likely defeat the enemy before you need to.
The Medic/Healer role itself has practically been rendered obsolete by Potions healing a lot of HP if you have the Grimoire Hat accessory equipped on your leader.
Saboteurs: Black Chocobo, Celicerata, Jihl Nabaat (DLC)
Synergists: Yakshini, Sazh (DLC), Purple Chocobo
Medics: Flanitor, Green Chocobo, PuPu (DLC)
Die for Our Ship: Alyssa initially suffered this just because she was shown being close to Hope in the previews. Then the fans actually played the game, and discovered she was The Mole and tried to kill Serah and Noel. It didn't help.
Disappointing Last Level: Academia 500 AF is a long platformer section with rotating platforms, switch puzzles, and enemies that are a jump in difficulty from the previous areas. It's often criticized for slowing the game to a crawl right before the final boss.
It was pretty large in XIII, but now that Hope has aged-up, oh, ten years, expect Hoprai shippers to be royally pissed if Lightning and he don't get together now that the can avoid otherwisesquickyimplications. Hilariously, by the time they actually get together in the next game, Hope is 14 again.
Noel and Serah shippers seem to be popping up everywhere as well, mostly due to the fact Snow left Serah in New Bodhum to look for Lightning and they work pretty well together during their travels.
Dragoons are a pretty good early example: capturing them is pretty easy, they don't take much materials to level up and their Strenght is generally double or triple that of Noel or Serah in that point of the game.
Getting Lightning's DLC episode as early as possible (and spoiling most of the ending in the progress if you don't skip the cutscenes) allows you get her as a monster ally at any point in the game if you 5-star both of her battles, which is pretty easy to do as the levels in her episode are independent from the main story. Pretty much all the DLC contents count as this, the Coliseum DLC alone allows you to get the best Ravager (Lightning), best Sentinel (Snow) and the best Saboteur (Jihl) monsters in the game.
While you can avoid enemies, some are just relentless. Some are as fast or faster than you. Others have a seemingly endless 'sighted you' zone. Why is this annoying? Well, from how the game's mechanics work, it means you have no other choice but to fight, whether you want to or not.
The Cie'th of Academia 400 AF, mainly because they won't go away and have a wide aggro range, leading to instances where you have no clue what you just ran into.
While some DLC are well-received, a part of the fanbase doesn't like how Square is implementing it by making some of it available and advertised on day one. Square has stated that this is the first title they're working on to have planned DLC in one of their titles from the start of development, which doesn't help their cause.
The scenario, especially the ending, led to a lot of bashing from the fanbase.
Iron Woobie: Lightning could be seen as this. She was erased from history save for the memories of a select few people, pulled into a chaotic, dead-looking world with no people and doomed to do eternal battle with her rival to protect Etro. And she ends up being Taken for Granite during the normal ending.
Jerkass Woobie: Alyssa, who is motivated by a legitimate fear of being erased from existence.
Most Annoying Sound: The slot machine makes a loud 'BA-DUNK' sound every time you get two Microchus in a row. Three Microchus is the ultimate jackpot, but you'll virtually never win it outside of Super Victory Mode. The game knows this, and loves to tease you with Microchus.
Once you get Victory Mode on the slot machine, Blinded By Light starts playing. Keep going and you'll get Super Victory Mode, and Eidolons plays. If you get a jackpot, the classic victory fanfare plays.
The 'click-click-click-click-click' that plays when you get a right answer on the Academia 4XX AF pop quizzes.
Offscreen Moment of Awesome: Much like it's prequel, this game contains backstory for events and characters in wikipedia-esque entries in the datalog and fragments. For instance, some fragments shed light on Caius' past. It would have been awesome to see him duking it out with his predecessor or performing the Incarnate Summoning of Bahamut.
Academia 400 AF, due to the high encounter rate and the fact that you can't run from any of them.
It's a great place to grind for CP and Gil if you need either.
Academia 500 AF as well. An unexpected platforming segment with long waits for platforms to get in correct positions (and featuring a few extremely difficult enemy encounters), the area was often criticized in reviews for slowing the game down to a crawl right before the big finale. Mapping the area to 100% is an even bigger chore.
Academia 4XX AF just because of the Captain Cryptic quiz. He'll randomly spawn in any area and the only clues you'll have are from the townspeople which isn't really helping that much.
A Dying World 700 AF, mainly because it's a bitch to get from one point to another, and there are tons of hidden treasure chests.
If you dislike the time distortion mini games, then you will HATE Oerba 300 and 400 AF. Running around the same small map playing the three distortion mini games *over and over*. Some of them have 6 stages, and there are 8 or 9 per time period.
The Hands of Time in the Time Warp Anomaly sections. Do you suck at math? Yes? Do we have a minigame for you. Some of them that have a time limit. Oh and some of them also are randomized as well. "Oh, but surely there's a guide"- Guide my ass! Every puzzle is totally freaking random!! Mitigated now that people have made multiplepuzzle-solvers for it. Of course, that doesn't improve the mechanic itself; just make it less annoying.
Ship-to-Ship Combat: Snow/Serah shippers and Serah/Noel shippers go pretty hard at one another.
Tear Jerker: The true ending, if you ignore the Soundtrack Dissonance, is this is a nutshell. Serah dies, Etro is dead and the entire world will die with her, Lightning is crystallized (by her own choice, as stated on a Fragment), and Caius has won.
The first battle against Caius, for those who haven't touched the sidequests yet. He can heal himself and buff himself up.
The Paradox Scope battles with Caius at A Dying World 700AF and the Void Beyond, with Serah (and Mons) and Noel going it alone respectively. If you're properly leveled with above average monsters in your corner in Serah's case he shouldn't be too much trouble, but he's not to be underestimated because he can still do alot of damage in short time. Weaker characters may be forced to use Wound, which reduces max hp (useful because once you kill him he instantly revives).
That One Sidequest: The goddamn Lucky Coin fragment. To get it you have to win 7,777 coins at the slot machines. And no one seems to be able to agree on whether that's a total number across all plays or all in one sitting (luckily losses aren't counted against that number), but either way expect to lose A LOT of coins, and thus gil in the process.
The Prada advertisements are getting in on it, despite the game being nowhere near it. Sazh's outfit, however, is getting universal praise. Lightning is generally well liked. It's Noel in particular that everybody doesn't like.
There is a cutscene near the end of the game with Noel, Serah, Hope and Mog on an airship. It has a more detailed render than the other cutscenes, and while every individual part of their faces is more detailed, the general effect is a little bit off.
When the trailer was first released, along with the logo picture, there was more than one person who commented on Lightning's "sexy female rival."
Many seem to be confused about Mog's gender (which is canonically male).
Villain Sue: Caius Ballad. He has some of the most powerful magic in the franchise, he's an immortal who cannot die, he can summon Bahamut, he can use a previously unknown summon method to merge with Bahamut, he's intended to be tragic and sympathetic, and is spoken of as a legendary hero who was only ever beaten once. His plan ultimately succeeds and he only dies because he wants it to happen, and in the next game he redeems himself by saving Yeul and going with her incarnations to watch over the Unseen Realm for eternity.
Yeul, or rather the many reincarnations of her. No matter which Yeul it is, she's born with the Eyes of Etro which lets her see the future and everytime she uses her powers (Which is often against her will), it slowly chips away her lifespan and she dies young.
Serah, due to having the Eyes of Etro as well. And the journey she takes ends with her death.
Noel as well. He's from a time after the end of the human race and is the last human and his only goal is to save humanity from extinction, even if it erases him from time.
