With the development of information networks, mobile devices, the competition for games has become increasingly fierce, and the research that Nintendo can occupy a more important position is mostly marketing strategies, and research on its own advantages and the promotion of its ideas is also essential. This study examines the factors influencing Nintendo’s game itself and its marketing to remain important in the gaming industry through interviews. The study found that Nintendo can occupy a very important position in the current fierce market competition, not only because of the market strategy that keeps pace with the times over time, but also because of the advantages of its games themselves: casual gameplay, carefully built IP, superior art, and the main idea of focusing on the players themselves in the publicity, which differentiates it from ordinary games and embodies them. Nintendo also differentiates itself from other consoles in the design of the Switch, eschewing the more competitive aspects and blazing a new trail. Nintendo’s care for players and observation of the situation gave Nintendo an advantage in market share.
