Educational games have become a mainstream trend in the education industry. This research represents a narrative language learning game "Mandarin Mystery," which uses a narrative structure in place of simple word repetition to teach Mandarin Chinese. This game combines stories, real conversation audios, and vocabulary exercises to help players learn Mandarin. In order to know if the game's method has an advantage compared to old-style learning---word repetition, this paper conducted a survey that compares Mandarin Mystery with a popular language learning application "Duolingo." Players are asked to play both of the applications and complete a survey about their opinions of each of them. The result shows players' preferences to both applications are almost the same, while Mandarin Mystery seems more attractive but Duolingo keeps its supporters through word repetition method and clean design interface.
