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: Fire Emblem Elibe
Anticlimax Boss: FE6 concludes with one of the more notorious examples of this. Idoun is barely any stronger than the boss that just preceded her, has less HP than said boss on Normal mode, can't do ranged attacks, and the Binding Blade destroys her so utterly that a moderately trained Roy can one-round her... and an untrained Roy, at his base stats with no more than promotion gains, can still take off 75% of her health by himself.
By the time you've found a way around Nergal's Story Breaker Power, you'll have a weapon capable of killing him in three hits. He is also killing you in three hits, though, so watch out!
In "Four-Fanged Offense" on Eliwood mode. Lloyd just stands there at the top of the map, waiting for you take him on, and has no way to fight back against ranged attacks.
Just how badly is Jerme this? Unlock the door Jerme is hiding behind. Park Merlinus in front of it. Provided he has levelled up half-decently, Jerme will most likely be unable to hit the cowardly man in the slow donkey cart blocking his way. Then send in your mages and laugh.
Specifically, his class amounts to little more than intimidation; his stats are low enough that he will probably never crit you, much less silence you. This is even true in the final chapter. The Morph in his image is just as laughable.
Awesome, but Impractical: Durandal and Sol Katti, in Blazing Sword. As powerful and cool-looking as they are, they're also absurdly heavy, and considering neither Eliwood nor Lyn are likely to have enough constitution to wield them without a massive speed penalty, you might as well let them use a lighter generic weapon instead so they can double attack (or at least, avoid getting doubled by the enemy).
Base Breaker: Marcus in Blazing Sword. At one part of the fanbase, he is a hated Crutch Character. At another part of the fanbase, he is regarded as Game Breaker. Working out his average 20/20 stats shows that probability leans towards the latter.
Marcus is this as well in Binding Blade. His growth rate is atrocious and his base stats, in relation to the enemy stats is not as good as his Blazing Sword version. However, he is necessary in the game's Hard Mode, and is especially useful to weaken the enemy to feed kills to your weaker party members.
Best Level Ever: "Cog Of Destiny" (Chapter 27/29 from Blazing Sword) is generally and genuinely regarded as one of the most intense, challenging, and goddamnedfun chapters ever programmed into a Fire Emblem game. The difficulty level earns a lot of respect for forcing many gamers to take genuine tactical measures, and the story elements introduced and/or developed during the chapter don't hurt, either.
Character Tiers: Hard mode and Hector Hard Mode bonuses (Characters that start as enemies in 6's hard mode and 7's Hector Hard Mode gain the same random stats boosts that enemies have) cause interesting and notable shifts in the tiers.
Cliché Storm: Binding Blade.. Evil nation invading the land, the ruler turns out to be a Disc One Final Boss with darker forces at work, and the game's cast largely follows archetypes set by the very first Fire Emblem title to a T (read below). Blazing Sword, however, did its utmost to avert this.
What's more, if someone were to watch gameplay/read info on the story and the characters of the Akaneia games, moreso Mystery of the Emblem, then you will find that Sword of Seals has some pretty glaring similarities to it. Just compare the appearances and stories to Wyvern Riders Minerva and Miledy. The story of Blazing Sword, which revolves around corrupt duchies and mercenaries, and deals with just how delicate the situation between humans and dragons has gotten for both parties, is considered to be one of the series' best plots for a reason. That, and the fact that the final boss is just a regular dragon. Not some great evil, or some demonic king or deity, but a really powerful dragon.
Crazy Awesome: Sain. Also Jaffar. The first time he is in a real battle, he is slaughtering enemies by the dozen. The only reason he doesn't kill more, faster, is because he lacks a ranged weapon, not that those archers stood a chance at hurting him in the first place.
"A Knight's Oath" and "Into the Shadow of Triumph", along with "Softly with Grace" (Black Fang Boss Theme), "Blessing of the Eight Generals", and Nergal's battle theme ("Everything Into the Dark") are all great as well. Can't forget "Together we Ride" and "Come, Join us" as well.
"Battle for Whose Sake" is an awesome Boss Battle Theme Music in a game where sounds quality was less than stellar.
Die for Our Ship: Thanks to the multitude of romance options, there are almost too many to count. Lowennote for Rebecca/Wil, Priscillanote for Raven/Lucius and others, and Niniannote for Eliwood/Lyn get hit pretty badly with it.
On the heroes' side, Canas and Nino both ranked very high in the popularity polls. Can't be a coincidence that they're related, can it?
Hector was so popular with fans that Ike was modeled off of him, according to the creators.
Lyndis. Not exactly the most relevant Lord after the tutorial stages, in fact her importance kinda waned after that with Eliwood and Hector taking center stage. She's STILL probably the most popular lady in Fire Emblem series. Also see, Germans Love David Hasselhoff.
Fan-Preferred Couple: Erk and Priscilla, helped by the fact that this is her only romance option with a happy ending.
Sonia and Ursula are popular with the Yuri Fan crowd. It doesn't help that Ursula's thoughts on Sonia are VERY easy to see as a Subordinate Excuseto the very end.
Jaffar/Nino is pretty much everyone's OTP in Blazing Sword.
Game Breaker: Arenas can get you theoretically infinite amounts of money and EXP.
The Luna Tome is the most accurate weapon in the game, has a high Critical Hit rating, and ignores Resistance, allowing its wielder to basically deduct its might and their current Magic stat from the target's HP. Given that the only two mages who can wield it, Athos and Canas, are considered to be some of the strongest in the game, it is not out of the ordinary for a Luna-Equipped Canas or Athos to defeat both final bosses in a round or two each. Because of this, Luna got a huge Nerf in Sacred Stones, rendering it circumstantial at best.
Elibe is also arguably the most popular Fire Emblem game to ROM-hackers. The fact that there exist more tools for hacking the Game Boy Advance games (specifically the Elibe games) should pretty much show that.
This is also why Lyndis is usually considered the best female in FE series, regardless of her waning importance in story. Having a BadassAction Girl for a Lord class for their Gateway Series really helps win her popularity in the Western regions, while her popularity in Japan is no slouch either (since in Japan, Shadow Dragon is a lot more accepted and Lyn has a lot more competition/predecessor from there.)
Goddamned Bats: While you're trying to kill the Dragon, there are Morphs positioned way out of reach trying to snipe at you with long-range tomes and status effect staves. Of course, they're not much of a concern if you either get everyone out of their range, or optimally, kill the Dragon in 1 turn (which is quite doable).
Goddamned Boss: The game neglects to inform you that the range for the dragon's fire breath is three spaces, not two like most ranged attacks. You can imagine how many deaths can be attributed to those not aware of this, and getting somebody fragile fried to a crisp.
Lloyd is this in Four-Fanged Offense in Hector mode. If you don't find out beforehand that not only has he moved to the middle of the map amongst hordes of other mooks, but that he also moves when approached, you're very likely to to pay for it with a dead ally. And the chapter objective is to defeat Lloyd, so if this happens too soon, it's either restart or miss out on the rest of the goodies in the chapter. Oh, and all this occurs in Fog of War. Fun.
In "Cog of Destiny" (either story), he's carrying an Iron Rune (negates your chance to crit), but magic swords don't crit at range either, so all it takes to win is a barrage of ranged weapons... but since he's a Swordmaster on a throne, good luck getting any to hit him. Something the game doesn't tell you is that if you send Nino up to talk to him (thankfully, he'll never attack her on his own), he'll actually move off the throne to attack any nearby units.
Dorothy from FE6. Her plainness/homeliness, particularly in the full artwork, comes from the fact that she has brown hair and brown eyes and brown clothes. Her sprite portrait gives her a less flattering haircut, too.
Vaida from FE7. The only thing that makes her less pretty than the rest of the female characters is the big scar on her face.
Ho Yay: Most characters in the 7th game have their endings changed depending on wither or not they have an A support with certain characters of the opposite gender. Except this is also true of the Florina/Lyndis, Lucius/Raven, and Marcus/Merlinus, relationships which are all same gender pairings. In fact, Lucius, Raven, Marcus, and Merlinus ONLY have their endings changed with these pairings. Also, Legault likes to hit on Heath. He says he's kidding, but he also says he's a liar... And he also sorta hits on Lloyd.
Iron Woobie: All three of the main lords in Blazing Sword.
Lyn vows not to cry, but there are entirely justifiable reasons why she can't always keep to it, such as when speaking of her tribe's slaughter and reuniting with her grandfather. She's faced with bandits, improbable odds, and prejudice for her heritage throughout her quest, but never hesitates to press on.
Eliwood is almost shattered by his father's dying in his arms and killing Ninian in her dragon form thanks to Nergal's trickery and Durandal. Almost.
Love to Hate: For a character only appearing in several scenes in Blazing Sword and being dead before Binding Blade, King Desmond's actions have sure earned him a lot of hatred. Of course, being responsible for trying to murder your own son at least two times - out of pure jealousy - and indirectly turning him into a misanthropic tyrant as a result tends to do that kind of thing to a character's reputation.
Mind Game Ship: The majority of Legault's supports indicate he likes messing with heads as much as he might like his support partner.
Moral Event Horizon: Sonia's is either her mocking revelation to Nino that she killed the girl's real parents or killing Brendan while mocking his love for her; you have your choice.
If you don't hate Ephidel when he stabs Lord Helman, and you don't hate him when he stabs Lord Hausen, you'll definitely hate him when he has poor Leila slaughtered, then has her mutilated corpse posed to look like it's still alive, just to mock you.
Nergal is no slouch either. Okay, so he has forgotten his and Ninian's true bond. It's not an excuse for mentally breaking her when she attempts to in-fight him (and with dialogue that sounds a LOT like a rapist mocking his victim), to the point of having her revert to her Dragon form and wander aimlessly until she's killed by Eliwood under the control of Durandal. And to twist the knife more, he appears in front of Eliwood after he has slain Dragon!Ninian, gleefully explains what happened, and mocks Eliwood's grief as the now-human-again!Ninian dies!
Scrappy Mechanic: Though it helps characters' fighting abilities, those of us who like shipping will get frustrated about character's having only one love interest and sharing that interest with another person in support conversations. It distracts from the game a little too much and it takes a VERY long time to get the supports done. Arguably made worse by the fact that not everyone's shared endings are necessarily happy.
Recruiting Vaida in Blazing Sword. If you spare her in chapter 24, you can recruit her in chapter 27. However, she comes with a entrourage of wyvren knights who don't back down when you recruit her. The entire mission is a VERY long gauntlet of fighting a lot of enemies and Vaida comes in very late in the chapter with VERY tough allies. If you have been trying to power level Nino or even have Eliwood a little too close to their position and you have no one around to rescue them, it takes two hits from a knight to kill either of them.
Bolting, Berserk, and other long range spells, moreso in Binding Blade than in any other game; nearly every chapter in the second half has several mages with Bolting hidden behind walls or swarms of enemies.
Building supports in all of the GBA games. They require that you tether two characters to each other for a long period of time (upwards of 240 turns for some characters) before you can unlock a support conversation. It's even worse in Binding Blade, where you can only accumulate a total of 120 support points for ALL characters in any given chapter.
Chapter 21 in Binding Blade. Reinforcements arrive every turn for 12 turns, almost all of them in a group of three wyvern riders and one wyvern lord. Also, the boss of the level is incredibly hard if the units brought are not experienced enough. To make things worse, you must finish this within 30 turns, or you cannot go to Chapter 21X and obtain the Apocalypse dark tome necessary for the Good Ending.
Chapter 14. Not one, not two, but three things to hinder your movement, plus enemies out the yin-yang, the forced deployment of two characters who can be easily killed, and treasures to find, one of which can only be found by one of those fragile units. Oh, and if you want the Gaiden chapter? You have to finish in 25 turns or fewer and keep alive one of the aforementioned fragile characters.
Chapter 7 in Hard Mode really stands out. Swarms of powerful enemy units, including cavaliers and mercenaries, storm your still developing army, a pair of wyvern riders with abnormally high stats for this point in the game will fly amok and pick off your weaker units (there's a third, but he'll only attack when you move into his range), and the three recruitable characters will quite often gleefully commit suicide (though Zealot can last a while, being a pre-promote and all). To top it all off, if you take too long and hang around the southern portion of the map, cavalier reinforcements will rush you, with one in every four always being a level 15 with a Silver Lance. Without proper training and supports, especially for Alan and Lance, this map can force a player to restart their entire file.
Chapter 16 of Binding Blade; aside from all of the irritating enemies with Bolting and Purge, there's a powerful enemy general running around who you must leave alive if you want to go to the gaiden chapter. And you can't simply rush through the level avoiding him, unless you want to skip all of the treasures.
Tier-Induced Scrappy: Marcus, being a Crutch Character, is often this. However, he can be quite useful to reach remote villages and rescue units (which gets them out of danger and weakens him enough that he will just miss one-shotting enemies, allowing other units to finish them off for the EXP).
Renault gets this too, being a Bishop recruited in the penultimate chapter with very poor magic stats for his level, though he has some good equipment.
Cecilia from Binding Blade. Although Valkryie is a strong class, she's not very powerful, has limited room to grow, and just to rub it in, she takes a massive movement penalty in her first chapter. It doesn't help that the previous Mage General was Pent, whose main downside was that he steals all your XP on his recruitment map and is outcompeted by Nino if you put a huge amount of effort into raising her.
On that note, Nino qualifies as well, for coming at Lv. 5 unpromoted ridiculously late in the game. Magikarp Power or not (her final stats are, on average, the highest in the game), that's a lot of Level Grinding. A big fissure between the Broken Base is whether Marcus or Nino is the best or worst unit in the game. Marcus is, admittedly, incredibly useful for tasks other than KO-ing units despite, statistically, having the worst stats in the game.
Rath, like the other Sacaean characters, can score critical hits like a madman, but otherwise, his stats are sub-par, even when promoted.
Jack of All Stats characters often don't do well in either games; Eliwood and Lowen get hit hard with this (Lowen as a cavalier is much like Eliwood with the other two Lords - cavalier Sain is one of the strongest physical fighters if used, and cavalier Kent is fairly fast and can actually develop high luck when promoted).
Eliwood's case really boils down to having to share the spotlight with Hector and Lyn. Compared to other lords outside his own game (including Roy, his own son), he fares much better.
Roy has pathetic base stats, unreliable growth rates, and a REALLY late promotion even by Fire Emblem Lords standards. While his promotion also give him an amazing Eleventh Hour Superpower in form of the Binding Blade, it did not stop him from being mediocre for the majority of the game. There is a good reason that he is almost always considered the worst Lord unit in the series.
Wendy and Sophia. The former's reputation as a Tier Induced Scrappy is outright LEGENDARY when compared to other Tier Induced scrappies in the entire series, which is saying something.
To clarify Sophia, she's similar to Nino but next to impossible to train since she joins at a point where nearly every enemy will kill her in one round. And unlike Nino, the result isn't all that worth it as her final stats are near identical to Lilina's, who was already a Base Breaker stat-wise. What makes players really hate her though, is that you're forced to use her in the chapter she joins... which happens to be a Fog-of-War Desert map with tons of flying enemies, and she has to survive to unlock the sidequest chapter, turnig the whole thing into an annoying Escort Mission.
What Measure Is a Non-Badass?: Eliwood is considered a pansy for being a Jack of All Stats (whereas Hector and Lyn specialize in strength and speed, respectively), and for being a Nice Guy who hates war and openly weeping when his father dies in his arms, and again when he mistakenly kills his friend/potential girlfriend Ninian. Because, you know, no real man would ever do that.
Lyndis gets hit with both sides of this trope. On one hand, she gets labelled as a "Strong Female Character (tm)" and becomes the yardstic to measure ALL the Fire Emblem women, who are often called "weak" and "useless" for not being ~hot and strong shit~ like Lyndis. On the other hand, "fandom feminists" believe that not having the spotlight on her through all the game and having several prospect love interests mean Lyndis is a weak woman who MUST have downplayed her skills to seduce men instead of being HBIC note HBIC: Hot Bitch In Charge 24/7.
The Woobie: Nino for having an abusive "mother" who orders her death and killed the girl's real family. Priscilla for her biological parents' deaths, brother's disappearance, and having most of her romances end badly. Nils and Ninian for, well, the whole plot of the game happening to them.
