Gacha games are a type of video game that incorporates a monetization system inspired by capsule-toy vending machines, known as gachapon in Japan. Players spend in-game currency, which can be earned or purchased, to receive random virtual items, characters, or upgrades. This element of chance adds excitement and encourages players to keep playing and spending. These games often feature a variety of characters or items, each with different rarity levels. Popular examples of gacha games include Fate/Grand Order, Genshin Impact, and Arknights. Players often collect and upgrade their characters to enhance gameplay and compete in various challenges.
