History YMMV / Planescape

* HilariousInHindsight: The name of members of the Society of Sensation, "Sensates", after the release of ''Series/Sense8''. The Sensates' signature gadgets, the sensory stones, are even designed to be a (limited, low-bandwidth) way of "sharing sensation" the way the main characters of ''[=Sense8=]'' do.

* CrazyAwesome: The Xaositects' speciality. They live in frequent flash-mobs where any number of them from one to "everyone able" may go hurl wild magic at Hardhead patrols or make a great art piece just because one of them felt like it at the moment and others thought it was a great idea. The Revolutionary League infiltrates other factions with a subversive intent? A Xaositect infiltrated ''them'' for years -- just for lulz.

* FanonDiscontinuity: You would be very hardpressed to find a self-described Planescape fan who likes 4th edition's "planar material", with the biggest sticking points being the replacing of the Great Wheel cosmology with the smaller, more compact and explicitly non-CharacterAlignment-based World Axis, and the insistence on using a post-Faction War version of Sigil. You are much more likely to find a 4e fan who likes the "planar fantasy" concept and feels the World Axis supports it better than a true fan of both 4th edition ''and'' Planescape. %%InUniverse

* MagnificentBastard: Duke Rowan Darkwood, the factol of the Fated, instigated the Faction War and afterward became one of the few people to ever escape from the Lady of Pain's mazes ([[Videogame/PlanescapeTorment The Nameless One and Ravel Puzzlewell]] being two others). Although the Lady of Pain ''definitely'' got the last laugh, since she trapped Duke Darkwood into an infinite time loop.

* EnsembleDarkhorse: Shemeshka the Marauder is an arcanoloth of AmbiguousGender and one of the biggest influencers in Sigil. On top of [[CardCarryingVillain reveling in her]] [[NeutralEvil Neutral Evil-dom]], her popularity is presumably one of the reasons why the arcanoloths became their own race (the Ravaasta) in 4e's World Axis cosmology -- and it's certainly why Shemeshka basically was established as having obtained her desire of becoming ''the'' most powerful and influential woman in Sigil's 4e version.

* ParanoiaFuel: Portals. They can be anywhere. Any opening can be a portal, from a door to a rat hole to the opening in a barrel to an arch over a street. Its impossible to be certain where one may pop up until someone stumbles by with that portal's key, which can be anything from a priceless artifact to a stray thought or memory. And they can lead anywhere, from Mount Celestia to Toril to any of the Nine Hells. It's an accepted risk to living in Sigil that one can trip right into a portal without knowing it and end up on another plane altogether. Just walking into your front house can lead you to the Ash Wastes. Even worse is the Hive, where ''any random puddle'' could be a one-way and permanently active portal to the Paraelemental Plane of Ooze.

** The Blood War is regarded by many fans as being an incredible, epic piece of background lore and iconic to the setting... and a significant number instead hate it, generally citing its PlotTumor nature. 4th edition ''TabletopGame/DungeonsAndDragons'' actually got rid of the Blood War as it used to be, ''because'' the designers felt it was overdone, over-hyped, and tended to overshadow everything else about Sigil and the planes.
** The Faction War is a deeply controversial aspect of the setting, resulting in deep divides between those who loved the original factions and those who loved the new ones.

** The Xaositects faction earns a lot of flak because their faction write up actually holds up ChaoticStupid as ''an ideal to live up to''. Needless to say, many [[GameMaster DMs]] ban party members from belonging to this faction.

* RetroactiveRecognition: One of the key writers for the campaign was Tony [=DiTerlizzi=], who would later go on to write Literature/TheSpiderwickChronicles (along with Holly Black) and the Literature/{{WondLa}} series, both of which later became favorites of children's literature.

* MoralEventHorizon: Rowan Darkwood. His plans to instigate the Faction War involved taking control over the Mercykillers. He couldn't do that without seducing Alishon Nilesia, who while being a KnightTemplar, was a 19-years old girl. After winning her heart, he persuaded her to marry him and involve him in her faction's chain of command. Then he sold her into slavery to the fiends.

* ButtMonkey: Every time the Paraelemental Plane of Ooze is mentioned it is described as a revolting and disgusting place where there's nothing to do and no profit to be made. As such it's often seen as the biggest joke in the Multiverse and rarely visited.

** Special mention goes to the Inner Planes. The four Elemental Planes can be scary enough (you fall until you die of dehydration, drown, get crushed or burned alive) and the Paraelemental Planes (the four planes between the Planes of Air, Water, Earth and Fire) can put one in the dead-book real fast by either freezing, corrosion, melting or suffocation. But it's the Quasi-Elemental Planes that get real scary. Here a berk can get roasted by lightning, fossilized, blinded and incinerated, boiled alive, burned by cinders, disintegrated, have all the water sucked out of your body or just die from exposure to a vacuum. [[SarcasmModeThings get extra fun]] when you land in the area where a Quasi-Elemental Plane borders another or one of the Para-Elemental Planes. And that's nothing to say about what the Positive and Negative Energy Planes can do to a body...

* EldritchAbomination: The Lady of Pain. No one knows exactly WHAT she is, but she does not count herself amongst the gods, and they sure as hell don't want her amongst them. And she's powerful enough that the gods cannot step into Sigil. AT ALL. Not a single one. And within its walls, she is ''absolutely omnipotent''. The laws of physics and magic are literally hers to command. If that doesn't scream eldritch abomination, what does?

* MoralEventHorizon: Rowan Darkwood. His plans to instigate the Faction War involved taking control over the Mercykillers. He couldn't do that without seducing Alishon Nilesia, who while being a KnightTemplar, was a 16-years old girl. After winning her heart, he persuaded her to marry him and involve him in her faction's chain of command. Then he sold her into slavery to the fiends.
