Quests 

Quests provide players with goals that aren't directly tied to game play, serving as a motivational tool. You can design quests to encourage behaviors players might otherwise overlook. For example, you could create a quest that rewards players for sharing the game on social media. Quests can also be used to monitor and reward a variety of in-game actions, such as opening shops, making purchases, crafting items, or accumulating specific resources. This system helps to engage players by rewarding their diverse activities within the game
