Fan Club Simulator is a board game designed to provide players with an immersive fan club experience. In response to the misconceptions about the culture of the fan club in China, we designed a game that enables players to participate as members of a fan club, using cards to gain high scores for their favourite Idol through strategy and interaction in a relaxed atmosphere. The game successfully restored the core elements of the fan club culture and was highly praised by players, helping them build a deeper understanding of the fan club.
