An idea came to me while speaking to Fanny Two-tricks in the Tarantia Commons. It seems that Fanny only takes your money and gives nothing in return (I didn't give her the 15 silver), but I thought that it would be great if you could get something from these kinds of NPCs (i.e., hookers). So, my suggestion is to include a Whoremonger achievement with a future revision of the achievement system. There are probably about a dozen quests involving whores in the game, not including whores with dialogue that do not offer quests. If a player completes all of the quests with whore quest givers and speaks to all of the NPC whores without quests (including courtesans and gigolos - we don't want to be sexist), then the player unlocks the Whoremonger Achievement and receives the Title "Whoremonger." The Whoremonger Achievement would be included in the category with the drinking and horse racing achievements ('Divergent').
I am serious and I really would like to see this Achievement included in Age of Conan, the only MMO with whore quests that I can think of.
