Individuals born in and after 1995 spend most of their time playing video games. The majority of video games have violent content. This study aims to examine the effects of personality traits and self-esteem on social ostracism among Valorant players. In this context, 83 Valorant video game players, 55 male (66.3%) and 28 female (33.7%), were reached online. The mean age of the participants was 21.49 and the age-related standard deviation was 2.03 (age range 18-27). Faceted Inventory of the Five-Factor Model, Self-Esteem Scale, Social Ostracism Scale, and demographic information form were used. Data was analyzed by quantitative analysis techniques, namely correlation and simple linear regression. Findings show a positive relationship between social ostracism and neuroticism; and a negative relationship between social ostracism, agreeableness, and self-esteem. Neuroticism (envy) and self-esteem significantly predicted the variance (41%) in social ostracism. Findings were examined in light of the relevant literature, and some recommendations were made.
