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: The Elder Scrolls IV: Oblivion
Alternate Character Interpretation - Plenty of people, even some in-game characters, just plain don't like the "good guy" Archmage Traven. Your interpretation of him and his apparent grudge against necromancy colors the Mages Guild quest line; from what it seems, while the necromancers are truly a threat, at least part of the Guild's fervent opposition to them is due to Traven's personal agenda.
There's also the fact that he closed the Imperial University and eliminated freedom of research, which is antithetical to the reasons the Guild was founded in the first place. Any more than a cursory glance has Traven as a man with a grudge against necromancy and is willing to do anything to destroy it, rather than an archmage doing what's best for the guild. It certainly doesn't help that most of the smaller guildhalls are run incompetently by Know-Nothing Know-It-Alls or people who were Kicked Upstairs.
It's mentioned several times that he severely weakened the Mages Guild. By the time of Skyrim it no longer exists, likely collapsing during the ensuing chaos resulting from the Septim bloodline ending
Most of the combatants are willing volunteers, and they can retire at any time (you can meet a few retirees, including Othimbar of the Cheydinhal Fighter's Guild, among others). Not THAT evil...
Regardless of whether they're volunteers, allowing people to fight to the death for entertainment is pretty nasty.
Mankar Camoran has a few odd things about him that makes him suspect to many players. Most notably, the historical Mankar Camoran was not an Altmer, while the one in-game is. He confuses several daedric princes and their realms. He is wearing the Amulet of Kings despite not being related to the imperial family (though events in skyrim could explain this). Many players suspect he is a false front for the Mythic Dawn.
Anticlimax Boss: Agronak Gro-Malog, the Grand Champion of the Arena. Agronak's level isn't scaled to the character level so at mid level and above he is easier the mooks you just fought in the Arena. Of course, all the NPCs still react to the fight as if beating him was a huge accomplishment. You can even beat him at low level if you do his quest.
Erandur-Vangaril, a lich with a backstory that has a bug that causes it to always have only 15 Health, and you can only fight it if you're at least level 23, at which point you can almost certainly kill it in one hit.
Mannimarco too. His mooks are slow and avoidable, he has no game in melee combat, and if you have a decent weapon, then he can be killed with a dozen or so attacks at the most.
He becomes even more of one for a player of Daggerfall, who likely would have expected Mannimarco, the King of Worms to look like the King of Worms (imposing, clad in a red robe covering his face in shadow, eyes glowing brightly). Oblivion's incarnation... is a fairly ordinary-looking Altmer.
Complete Monster: Mankar Camoran, the leader of the Mythic Dawn cult and a worshipper of Mehrunes Dagon. During Oblivion, Mankarís goal is to summon his master into Tamriel so Dagon may destroy the world and create a new one in its place, one that coheres with Camoranís Social Darwinist beliefs. Not only does Mankar aide Dagonís Daedra in attacking the mortal world, he also orchestrates the assassination of Emperor Uriel Septim, as well as his children. He even had the city of Kvatch completely destroyed in a failed attempt to kill Urielís bastard son, Martin. While Mankor lures in his followers with promises of a paradise for their faithful service, this turns out to be a lie. Seemingly idyllic on the surface, Mankarís ďParadiseĒ is really a hell where his followers are constantly killed by monsters, only to be resurrected and killed over and over again. His promise to allow any follower who loses faith to leave his paradise also proves false, as the grotto, which is said to be an exit from the afterlife, really leads to a torture chamber where the unfaithful are made immortal, locked into gibbets, and then dumped into lava. One follower who lost faith was forced by Camoran into inflicting this punishment on his friends over and over again. Paradise is said to be Mankarís vision of how he believes the world will be once Dagon takes over.
Crazy Awesome - Sheogorath is, almost literally, practically the embodiment of this trope. For example, if you attack him, he executes you by teleporting you hundreds of feet above the Isles, just to fall to your death!
What makes this more awesome? It's said that you're not really falling thousands of feet to the ground, Sheogorath's throwing the planet at you!
To be more specific: Will-o-Wisps, who are, count 'em: magic resistant, fast, turn invisible, can only be hurt with silver/magic weapons, drain stats and can make your weapons/armor rot off your body. And Spider Daedra are literally giant deadly demonic spider-women. Who spawn miniature versions of themselves that paralyze you, so they fit the trope too.
Designated Hero: If you think about, Traven really is not a very good Archmage. His very first act upon taking the position is completely outlawing Necromancy in Cyrodiil after centuries of it being tolerated and he expelled and blacklisted over half of the Council when they protested. He forces the Arcane University, one of the greatest learning centers in Tamriel, to close its doors to all but the highest ranking guildmembers, which completely contradicts the guild's original purpose. He's made the guild sever ties with any organization that so much as tolerates necromancy, putting a serious strain on both manpower and resources. Finally, the main reason he seems to hate necromancy is because it involves stealing the souls of living beings, but its explicitly stated that they didn't start doing this until after Traven's draconian policies came into effect. There is no denying that Mannimarco is evil, but its all but stated that the only reason his Order has become so powerful is because Traven's actions allowed his ranks to become bolstered by hundreds of disgruntled mages.
Once Mythic Dawn agents start openly attacking people, it's possible for one such agent, Cingor, to be rendered not just peaceful, but friendly with a high enough influence in the Fighter's Guild.
One of the rather hilarious ones involves Shadowmere, the horse you can get during the Dark Brotherhood questline. Unlike all other horses she's marked as essential and cannot be killed, only briefly knocked unconscious. It is still possible to access her as if she was a corpse, though, and as with all other bodies it is possible to place items into her inventory, essentially turning her into a portable storage chest. Furthermore, placing potions into her inventory will cause her to actually drink them during battle, enhancing her already considerable combat effectiveness.
Although not useful quite hilarious. At the Arcane University Casting a frenzy spell on a mage scholar or apprentice will cause them to attack each other and the intervening guards. After the spell has worn out the hostilities between the scholars and the apprentices still exist and the will fight till the last side standing. Because all parties are respawnable they will all come back after leaving the university for a while. The end result is a scholar vs apprentice rumble every time you return from your quest.
When the avatar of Mehrunes Dagon appears in the middle of the Imperial City in the finale of the main storyline, you aren't supposed to fight him, and he has the stats to make sure that you won't. However, the Wabbajack works on him, and if you get lucky with it, you can turn him into something harmless and easily killed, like a sheep. And when you do kill him, he melts.
After the Fighter's Guild mission "Trolls of Forsaken Mine", upon asking for your next mission, you're demoted because the Guild Master blames you and Modryn Oreyn for the death of her son. So you're forced to do an extra mission to regain your rank. However, this only happens if you go to Anvil's Guild Hall to ask for your next mission. You still have to do the extra mission, but you don't lose your rank (so it's really more like extra credit).
If you are suspended from the Mages' Guild, you are required to gather alchemic ingredients for Raminus Polus to get back innote 20 Dragon's Tongues abd 20 Redwort Flowers for theft, 20 Vampire Dusts and 20 Daedra Hearts for murder. If it's your first offense, a glitch allows you to get back in if you collect 20 pieces of only one of the required items.
Ho Yay: From Knights of the Nine, Sir Berich and Sir Caius. Despite having been killed by the former, Sir Caius seems oddly eager to clear Sir Berich's name and enter Afterlife with him. Sir Berich seems equally excited about it.
Since Martin seems to develop a crush on the player, this happens if you're playing a male character.
The blacksmith in Mania will hit on the player if you're a male character. Did I mention this blacksmith is a male Orc who thinks he is a young human girl?
Implied Les Yay with the blacksmith in Dementia as well.... she will hit on the player after becoming Sheogorath, even if you're female.
Misaimed Fandom - Mannimarco and his Order of the Black Worm are only a small niche of Necromancers, and yet some fans believe they represent Necromancy as a whole...
Partly because the game paints them as it. It takes looking closely at the lore, or alternatively having played Daggerfall or Morrowind to realize that Mannimarco's Order doesn't represent the general tendencies of necromancers as a whole.
Moral Event Horizon - Mannimarco destroying the Bruma guildhall in the Mages Guild questline, The Blackwood Company killing the guildmaster's youngest son in the Fighters Guild questline, and Umaril slaughtering multiple Chapels in Knights of the Nine.
The protagonist can cross this in multiple ways, the most obvious choice being any quest offered by the Dark Brotherhood [the best choice is the one where you kill all of your guildmates, even the guy who initiated you is disgusted by it (though mostly because of your idiocy for helping the antagonist of the guild chain)]
Fixing Xedilian normally doesn't sound bad... but consider this: It's standard MO is to either a)kill off greedy adventurers, or b)render them irreversibly insane. Points for the creativity of said Mind Rapes. Hallucinating into believing that the rat you just taunted is now going to murder you, searching a hundred duplicate keys to see which one works, and worst of all, a forced temporary and literal out-of-body experience. But hey, the Shivering Isles always needs residents...
Most Annoying Sound - Including random villagers talking about mud crabs, and shopkeepers telling you how great you are at haggling.
Paranoia Fuel: Some may be uncomfortable if you don't know what the "Your killing has been observed by forces unknown" means.
By the time you're done with the Shivering Isles questline, you will have become very wary of corpses in case they're not quite dead.
Player Punch: The Dark Brotherhood questline contains a very, very nasty example of this. By the end of the quest line, every single member that you knew at the beginning is dead.
Martin in the main quest.
Viranus Dalton and Biene Amelion in the Fighters Guild.
Sheogorath in the Shivering Isles.
the Bruma guildhall, and everyone in it, getting blown up by Mannimarco during the Mages Guild questline.
The disposition roulette can be this until you learn how it works, and even then your speech make certain thing Lost Forever, thankfully bribing enough can cover you if you fail.
Squick - One alchemist asks you about the punishment for necrophilia in Cyrodiil. "No reason, just curious." She'll be very happy if you tell her it's just a fine, even for repeated offenses. What makes it even worse, however, is that she makes the comment that the punishment is "much lighter than Morrowind," leaving the impression that she may be in Cyrodiil because of her... habits. There's even a line from an NPC about seeing a Dark Elf walking out of the graveyard at night with "a silly smile on their face." Pass the Brain Bleach.
Also worth noting that the Player Character knows what the punishment is. Perhaps one step on the trail of discovering why you start out in a dungeon at the beginning of the game.
Although, one quest shows the Player Character knows the punishment for grave robbing as well, so maybe they're familiar with the laws of Cyrodiil. (The punishment is death, by the way)
That One Sidequest - Collecting 100 Nirnroot plants. "You must have turned every stone in all of Cyrodiil". Yes, yes, we did. Though it's not quite as hard as it sounds- there are over 300 nirnroot plants in the game (they can be used in alchemy) so finding 100 isn't too straining. Three of the DLC add-ons include extra nirnroots too- and the one in Deepscorn Hollow respawns every 3 days as it's a "collected" food object on a desk, rather than a plant.
Shadowbanish wine. All you're told is that it is found in abandoned forts around Cyrodiil. There are over fifty forts, only about a dozen of which have the wine in them. Good luck.
And one of those, Fort Grief, isn't even accessible unless you're doing the associated quest.
In a similar fashion, especially if you're not into random dungeon searching, the Museum of Oddities in the Shivering Isles expansion.
This one is actually annoying, difficult, and up to random chance, simply because the artifacts show up as random loot in chests and can't be found in specific places. The same goes for the Amber and Madness matrices, as they're only found in random chests.
Even worse, the "Sheogorath Shaped Amber" is only found by random chance in non-respawning containers. So there's a chance you may never find it, making the quest unwinnable. Like many other problems, a mod fixed this by making it possible for it to appear in Gnarl Elders. It's still rare, but not Lost Forever.
Maglir, the biggest coward in the fighter's guild. Getting to splat him is satisfying. That is, assuming a bug in the game doesn't kick in... sometimes he's not properly removed from the Fighter's Guild faction(may be related to OOO or another mod but it has been reported in vanilla environments) and killing him will get you expelled when you return to Chorrol.
Farwil Indarys. His irritating gameplay-related "qualities" are even lampshaded by the Count of Cheydinhal, Andel Indarys... his own father.
Take That: M'aiq the Liar delivers a subtle one about another western RPG: "Everyone enjoys a good fable. M'aiq has yet to find one, though."
They Changed It, Now It Sucks: Cyrodiil was previously described to be very Oriental and Mesoamerican inspired Roman Empire While the more Oriental and Mesoamerican aspects of Cyrodiil were being downplayed and the Roman ones emphasised in Morrowind, this game completely disregards all of that and turns Cyrodiil into a very standard Medieval European Fantasy, with only vaguely Romanesque bits. Not everyone was happy.
Uncanny Valley - Some of the NPCs stare at you bug-eyed throughout every conversation. Without mods, almost every human face looks blotchy and blurry, like they paired high-poly models with Voodoo-era textures. Zooming in for conversation with any non-Argonian (especially Redguards!) immediately reminds you that you're playing a videogame. They really should have spent a few more megabytes on face textures.
Villain Decay - It hits Mannimarco rather hard. Throughout the Mages Guild questline, he is set up as the Big Bad of that story, having characters become unnerved or outright terrified by knowing that he has reappeared, there's a pretty good poem-style book about his history to find which sets him up as a powerful evil, at one point, he deals a scarily effective, unexpected blow to the Mages Guild and the only survivor of the attack is terrified and tells you how he, concealed by magic, watched Mannimarco rip out his friend's soul and how he believes the guy actually could see through his magical disguise and pretty much just spared him for fun. Then Mannimarco effectively manages to corrupt and disrupt the Mages Council. By the end of the questline, you seriously get the feeling that everything's going to hell for the Mages Guild if you don't stop him quickly. So, after finding his hideout and slaughtering your way through his minions, he's a moderately powerful Altmer wizard whose spells might be slightly threatening at the very worst, and silencing him will reduce him to waving a dagger at you.Yep, this is the guy who Hannibal Traven thought was such a threat that he voluntarily soul-trapped himself to give you some sort of advantage.
What Do You Mean, It's Not Political?: In the book "The Eastern Provinces", the author gives a very disapproving critique of the Empire's costly occupation of Morrowind and the Black Marsh, citing how wasteful it is to spend taxpayer money on troops stationed there and how the rather than putting an end to the despicable human right violations (slavery), the Empire is only interested in the valuable black natural resource it can exploit from the lands (ebony), and how keeping on this track will lead the Empire into financial ruin.
