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.
Creator Worship: Not to cult-like levels, but the dev team has been very, very open and communicative about the game's development, including going into the rational behind potentially unpopular stuff such as Money Sinks, and actually listening and responding to suggestions and concerns. The fan base has reciprocated with appropriate levels of adoration for this unexpected honesty.
Creepy Awesome: The Mordesh, to their fans. Just creepy to most everyone else.
Evil Is Sexy: While the "Evil" part is up for debate, no one can argue that the Dominion exert control over the galaxy in style.
Fan Dumb: There's quite a bit of outrage over the lack of body sliders in character creation, with some commentors accusing Carbine of sexism. The actual reason for the lack of body sliders is that Carbine has to model gear for every body type individually — and given the races and genders available, there are already fifteen separate body types.
The Stormseeker Pell. You unintentionally deliver poisoned supplies to them, killing them all. You played with their children. You helped them with their chores. You earned their trust. It's one of the first missions in Ellevar, so pretty much any new, uninformed player will do this quest arc.
On the Exile side, there's the fate of Deadeye Brightland's family, wiped out by a dominion artillery barrage moments from getting away to safety. They were going to name the kid after you, too.
