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: Fable III
Complete Monster: The Crawler is pure death and destruction. If you don't need more convincing, when you first encounter it with Walter, it mind rapes Walter and then tries doing the same to you. After it forces Walter to relive a traumatising time in a cave it is revealed that it massacred the residents of Aurora and taunted the survivors. Then after it attacks Albion it will massacre 6.5 million if you haven't donated enough gold and and then possesses Walter, forcing you to kill it by killing Walter. Most Eldritch Abomination kind of creatures would operate with Blue and Orange Morality and be exempt from this as a result. However, the Crawler takes glee in this (or at least its perception of morality is not properly explored) and qualifies.
The Hero of Brightwall in the third game can be this as a monarch. As one achievement is to make a royal decree while dressed as a chicken, this is highly likely to come up for most gamers at least once.
That's one of the best ways you the player can create Narm.
Disappointing Last Level: The build-up to the Crawler invasion takes an enormous amount of time and money if you want to do it the good way, but the invasion level itself is extremely short and culminates with an easy boss fight.
Ensemble Darkhorse: She only appeared in one trailer and the opening, but the Rebellious Chicken captured the hearts of all who knew her. Rest in peace, noble chicken - you shall be avenged.
Not Quite Dead - A black soot chicken scurries out of the kitchen at the beginning of the play-through. If you have the patience to follow her long enough, she leads you to a silver key chest in the garden.
Fridge Brilliance: Logan's monologue about how Albion is his to mold and shape sounds evil at first, till you realize that his threats are actually facts based on when the Crawler arrives and slaughters all of Albion.
More specifically, that Albion is his and the people will do what he says or they will die. He's more right than you could possibly think, and NOT in the figurative sense either. It's just that he's not going to be the one to kill them.
Reaver, who's considered a Karma Houdini, falls under this once one remembers/learns that he's also a Hero, and Heroes don't have to be good, as many players can attest to (and players can be just as bad, if not worse, than Reaver if they choose to be). Heck, he even has the dark circles around his eyes that the Hero can gain by being evil enough.
Good Bad Bugs: When the Hero has sex, it doesn't stop other NPCs from playing their standard interaction dialogue if they wander in the room. Having your child demand a toy or your wife coo "Oooooh, nice doggie!" during sex is absolutely hilarious. Although, your son screeching "I want to come, too!" shortly after your wife's first moan during the blackout can be... somewhat disturbing.
Iron Woobie: Supremely. The game really gives Walter hell.
Moment of Awesome: Technically speaking, Jonathan Ross gets killed by Balverines while Stephen Fry smugly ignores his cries for help.
Moral Event Horizon: The player can cross it by ruling Albion like a tyrant, then taking the money he/she gained over the year for said deeds and hoarding it as personal wealth, leaving Albion completely exposed to the Crawler attack.
Most Annoying Sound: The little comments the gnomes make, particularly if you can't figure out how to get to them.
Rewatch Bonus: There's a short cutscene early in III where Logan scowls over a map of Albion and makes typical tyrant threats ("These cities will bow to my will, or they will burn"). Once you learn of the Crawler and Logan's true motives, this scene comes across completely differently.
The Scrappy: Hobson. He's a money-hungry Jerkass who never stops complaining about you spending money for good causes even if you have triple the amount of gold required to save every civilian in Albion.
Unfortunate Implications: If you reach the max weight possible and wear pajamas, one Demon Door will proclaim you to be the most hideous thing he's ever seen. Considering that people will still tell you that you should be a model if you're skinny and wear pajamas, the Demon Door's words are likely not a criticism of prancing about in your nightclothes.
They Changed It, Now It Sucks: Fable III's streamlining of quite a few of its predecessor's features, especially its combat system. Which wasn't exactly the most complex to begin with either.
Villain Decay: The Crawler is introduced as a formidable Eldritch Abomination with a dungeon crawl that manages to get genuinely scary. The end fight against the possessed Walter... yeah, not so much.
Somewhat justified by the fact that it's implied that the Crawler cannot harm people directly beyond corrupting them with darkness — it takes over Walter's body and sends its "children" after you because it can't do anything else personally. And it's also implied that it took centuries for the Crawler to amass the force necessary to assault Albion.
The Woobie: Professor Faraday. Imprisoned by Logan for refusing to turn his machines into war weapons and forced to see his life's work changed into something he never wanted.
