Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang memengaruhi minat beli dan minat bermain dalam aplikasi Mobile Legend, yaitu aesthetic design, avatar identification, co-creation, dan authenticity. Penelitian ini menggunakan metode kuantitatif dengan pengumpulan data melalui kuesioner elektronik Google Form yang diisi oleh 251 responden. Data dianalisis menggunakan aplikasi Amos dan SPSS. Hasilnya menunjukkan adanya hubungan positif antara authenticity dengan minat beli virtual item. Namun, aesthetic design, avatar identification, dan co-creation tidak mempengaruhi authenticity, dan authenticity juga tidak memengaruhi minat bermain dalam aplikasi Mobile Legend. Lalu disarankan untuk peneliti selanjutnya agar dapat menambahkan variabel lain yang berhubungan dengan purchase intention, atau mengeksplor sektor industri lain atau aplikasi game online lainnya. / The purpose of this study is to determine the factors that influence purchase intention and play intention, which consist of aesthetic design, avatar identification, co-creation, and authenticity in the Mobile Legends application.
