Crafting systems are mechanics in video games that allow players to create new items or enhance existing ones using various resources. Players typically gather materials from the game world, such as wood, metal, or herbs, and combine them through a user interface to produce weapons, armor, potions, or other useful items. These systems encourage exploration and resource management, as players must decide which materials to collect and how to use them effectively. Crafting can also enhance gameplay by providing players with unique items that improve their abilities or help them progress through challenges in the game.
