Angst? What Angst?: The final chapter begins with Class Zero returning to their Academy to find it in ruins with the corpses of their classmates littering the halls. They barely seem to notice, and in a cutscene a few minutes later are bantering with each other like normal.
Anti-Climax Boss: Unfortunately, similar to Yu Yevon, the Final Boss is impossible to die against. However, it's not as bad a case — while Yu Yevon was practically a joke of a boss, this time the boss actually needs a semblance of strategy to beat. It's just that he can't kill you as you whittle him down.
Bizarro Episode: The transition to the final chapter. With very little foreshadowing or build-up, Finis happens, envoys of the fal'Cie appear to massacre the world's citizens, and Cid departs to a temple that's appeared to usher in the end of the world. With the rest of the story up to that point being straightforward and simple, this sudden swerve makes the finale seem quite detached from the rest of things. There is some talk before about how one nation uniting the world would bring in Finis, but if you miss it you'll be wondering what's going on.
Judging by the comments on the Final Fantasy Answers, the huge amount of characters seen as Expies has only gotten negative reviews. Some say they won't try the game just because of this, others say it's too soon to judge. It's not the first time fans of Final Fantasy choose to hate a game just because of its character design.
The game's announcement sent fissures through the fandom. The official announcement at E3 2014 came mere days after the fanmade English patch was released, and Square Enix sent a C&D to the creators to pull the patch. They did, but this being the internet, it's still out there and fans who want it can still find it. Behind the scenes there was a lot of drama, namely that SE had repeatedly tried telling them to not finish the patch weeks prior to E3. Further, the team felt the patch was not ready for such an early release (the final version that was put out has spelling errors and some parts left untranslated), but the leader of the team did it anyway, because according to rumors he knew or at least strongly suspected the official translation was to be announced at E3 and he wanted to push the patch out before the announcement. Was SE protecting their investment with the C&D or spitting on hardworking fans? Was the patch's early release just the creator wanting to push his team, or was he trying to stick it to the company? Should SE have even gone for an HD release or just translated the game for PSP to save time and money? What's more, the actual announcement was botched, as it was first announced that Type-0 HD would be for the Playstation Vita, and then corrected to PS4/Xbox One. Fans of the Vita took this as a massive middle finger, along with the general lack of attention given to Vita at the event. Suffice to say, this game's release is a touchy subject among those familiar with the week leading up to E3.
Game Breaker: The Regal Crown accessorynote Obtained from the Class First Moogle after playing for 70 hoursdoubles a characters MP and boosts all Magic stats by 40. The Akatoki Amythestnote Obtained from Celestia during the Milites ceasefire in a New Game+ if you got all five extra Classmates Zero increases all Magic stats by 100 and applies a permanent Quick status. Rem Tokimiya is a Black Mage who starts off with Twinspell and has more natural MP than any other two Classmates Zero put together. Give her the crown and the jewel, equip her with a Blizzard/Thunder spell (depending on whether you're fighting Concordia or Milites) and Fire spell of your choice, put on Avoid to deal with the Squishy Wizard end of it, and you have yourself a Vermilion goddess of war.
Rem is overpowered in general. It only lasts a short time, but her Undying Wish ability casts Reraise on the whole party, and even better, allows Rem to be revived after summoning an Eidolon.
Diabolos-class Eidolons are sold on their Gravity Master abilities, which fall under Awesome, but Impractical. What the Rubicus doesn't tell you is that the devil's movement is a swarm of bats that makes one think of the Batman Begins "backup" scene at Arkham. It's difficult to tell if the Eidolon can even take damage in this statenote He can, due to the fact that contact with an enemy results in Diabolos dishing out Collision Damage with a Life Drain effect.
Ho Yay: KURASAME X KAZUSA. Also, Ace x Machina, Jack x Eight, and King x Nine.
In the first light novel there's an entire chapter dedicated to Ace and Izana, in which the latter describes the former as having a "pretty face that could be mistaken for a girl's".
In-Universe example. In the Alternate Ending, Sice has feelings for Kurasame which she put into a love letter, but she's too nervous to give it to him. However, she accidentally presents it to Seven. It gets even more funny when the latter actually considers the relationship.
And when you get a Game Over, your character is surrounded by a blue smoke ...which almost means the enemy is going to do the same thing with you...until NPCs in the game say that only the Magic Bureau, Class Zero cadets and black market traders know how to gather Phantoma, or even know it's existence
The Scrappy: Many hate Machina for his Wangst over his brother's death, being cold and often lashing out at Class Zero except for Rem without listening to them, being The Mole to his classmates for a basically paranoid council, his Face–Heel Turn and his slaughter of his fellow Suzaku (never mind that it's partially because of his memory loss), revived at the end while the rest of the Class Zero students are dead, and effectively becoming the leader of Orience without being called out for any of his wrongdoings.
Throughout the world map save for just around the Academy, you can find Grand Horns wandering around. You're told to avoid them because if they see you they will chase you and you cannot outrun them. When they catch you they're Level 99 and capable of killing your characters in one hit, and are immune to damage unless you nail a kill-sight on them, which still takes a lot of hits to bring them down. They also always attack in pairs so getting an opening to try and hit them isn't easy. This means on your initial playthrough at the least and likely into New Game+, if you wander too close to these guys and they start chasing you, you basically have to let them kill your three lead party members so the battle will end.
One of the optional Special Order objectives you'll get on missions is "don't die for X number of minutes." The problem is that once you kill all enemies and combat ends, the SO timer keeps going. Despite the fact you can't die anymore (even status ailments are unlikely to do enough gradual damage to cancel out your innate regen when you dismiss weapons), you still have to stand around and wait for the timer to expire to get credit for meeting the objective.
That One Boss: The Dragon Egg, fought at the end of an Expert Trial late in the game. It has very high HP, requiring fifteen minutes or more of constant attacks to whittle it down. Except it summons an endless horde of dragons to attack you and distract you, so constant attacks is a tall order. The fight can take half an hour, and comes at the end of a Marathon Level with nine floors of fortress to run through. It's even worse on higher difficulties — on Finis, where beating the Egg is needed to unlock Holy, the dragons reach Level 100.
That One Sidequest: One of the optional combat exercises in subsequent playthroughs has the party storm a base like always. Except when you get to the boss, he runs off through the base and a Crystal Jammer field activates. For the rest of the mission, all magic is useless, but also all items are useless, which basically means no healing unless you have a Drain ability equipped, and only a few characters have those anyway. You don't even regen when standing still like normal. Have fun playing through the rest of the mission with no healing or buffs.
During the Code Crimson mission for Chapter 4, Mission Under Ceasefire, there is a Special Order to defeat the boss of the mission, the Sledgefist Giant, without letting any Milites soldiers die. At the recommended level, this thing is ten levels higher than you are - it can just about kill your cadets in one hit, non-Breaksight strikes hardly even scratch it, and the Militesi are outright suicidal, running straight up to the monster. The end result is that you have to Quick your party leader, charge up the Vermilion Bird, and pray you use it before the White Tigers kill themselves.
A surprising number of supporting characters are sidelined in the game. Outside of Class Zero, Kurasame, and Arecia, you can count on one hand how often most other characters appear beyond NPCs to talk to between missions. It's a pity, too, because they seem rather interesting and could probably contribute a lot to the story.
Despite the prominence of the four main powers in Orience, the Loricans are all but wiped out early in the game.
Tier-Induced Scrappy: Any character not named "King," "Cater," "Ace," or "Trey," is much weaker in battle than those four characters on account of their ranged attacks. There's a large number of flying enemies in the game, as well as enemies that attack from balconies and towers, so using ranged characters is just plain smart. The melee characters need to rely on ranged magic to hit back, otherwise they're helpless and the game becomes significantly harder.
Woolseyism: The Japanese name for the final dungeon is "Palace of All Magic." The fan translation, and later the official translation, went with the much simpler and striking (not to mention familiar) "Pandæmonium."
