Quests refer to tasks that a player must complete. Often, a reward awaits at the end of a quest. The quests are designed to guide a player through an area and often tell interconnected heroic deeds. They represent an important part of the gameplay in most MMORPGs and are the central aspect of solo PvE during the leveling phase. There are different types of quests depending on whether they are repeatable tasks (Daily Quests, Weekly Quests), the main missions (Main Quest/Story Quest), or side quests (Side Quests, Drop Quests, etc.). Additionally, quests are classified based on what the quest is about, meaning what the player has to do (Kill Quest, Collect Quest, Fetch Quest, etc.).
