Game Master is a family-owned game store that has been in operation for decades. The owner is described as easygoing and helpful, providing a welcoming environment for customers. The store offers a variety of card games, including Magic: The Gathering, Yu-Gi-Oh, and Pokemon. While the store no longer sells video games, which some customers find disappointing, the reviews praise the fair prices and helpful staff. The Magic: The Gathering community at the store is particularly praised, with a diverse player base and a focus on enjoying the game. The staff, including Justin, Christian, and Lilly, are described as friendly and responsive, though the lack of an online inventory can be frustrating for some customers.
