In the most general sense, a quest is a "hunt for a specific outcome", in contrast to simply winning a game. Typical quests involve killing a set number of creatures or collecting a list of specific items. Some quests may take only a few minutes or hours to complete, while others may take several days or weeks. Often, the larger the reward, the longer the quest takes to finish, and it is common for a quest to require characters to have met a certain set of pre-conditions before they are allowed to begin.
