Draco in Leather Pants: Vico. Considering what a twisted individual he is, even with his Freudian Excuse, the fact that he has so many fans and almost all fanfiction writings for ADWR seem to have him as the Princess' romantic choice and give him even more freudian excuses, is... disquieting.
Good Bad Bugs: At the end of the Golden Chalice quest, there is a glitch in the Hyath dialog which allows the Princess to gain infinite xp, gold, and reward weapon/armor.
Ensemble Darkhorse: Simon is very popular for being a badass prince who always treats the Princess with courtesy—at one point the two of them are trapped together, butt-naked, and while he's obviously attracted he respects her personal space and doesn't try to force himself on her. He is the only male in the game who does this. Add in some surprisingly cute Ship Tease and you've got players wishing he was an actual companion and Love Interest.
Les Yay: Aside from a possible relationship with Pia, the Princess can have a sexual encounter with 2 female Non Player Characters in Part 2, not to mention an... interesting way of recovering the hidden key from Tarleth in the "Captured" sidequest, which she obviously enjoys.
Most of the opening sequence. And Caron and Tony Blake's deaths. And the Dhorn assault on the Bear Pit, killing or capturing all of the members of the thieves guild. And more.
A rather unusual, but nonetheless effective usage: At the beginning of part 2, chapter 6, you lose all the shiny magical gear that you have been collecting throughout the game in a very taunting manner: you still have it, but it loses all of its special properties—weapons and armor revert to their basic models, potions won't heal, magic items won't work, etc. Your equipment may not be a character itself, but you grow attached to many pieces and come to rely on them like on a trusted party member, so seeing them suddenly turn into a pile of useless junk that you have to leave behind (because even the bags of holding stop working and you're probably immediately over-encumbered) can be devastating.
Strawman Has a Point: Sort of. When one of the Dhorn explains their beliefs that a woman should have a husband to protect her and stay at home, the problems with that are obvious from a modern perspective. But if your character is not into Anything That Moves, and after days of walking the streets of Molester City, it seems a bit inappropriate that the only way line she is given to report what was presented as a vision of stability and security is one that expresses great personal annoyance with it.
