The "Wish System" is a feature commonly found in video games, particularly in gacha games like Genshin Impact. It allows players to spend in-game currency or real money to obtain random rewards, such as characters, weapons, or items. Players can make wishes to receive these rewards, which adds an element of chance and excitement to the gameplay. In many games, the Wish System includes different banners or events that offer unique rewards for a limited time. Players often strategize on when to use their wishes to maximize their chances of obtaining desired items or characters, making it a key aspect of the gaming experience.
