Digital games are increasingly used in education to boost engagement and reduce stress. Digital game-based learning (DGBL) has improved the learning experience. However, further investigation is needed to determine the specific impact of commercially available, off-the-shelf (COTS) video games on English language skills. This study provides a comprehensive overview of DGBL literature, specifically focusing on how COTS games enhance English language skills in ESL and EFL classrooms. The systematic review methodology, following PRISMA guidelines, involved searches across database like Scopus, Springer, Science Direct, and Web of Science, and other sources, and 16 articles were selected for detailed analysis from 19,201, screened articles. The systematic review examines the positive impact of commercial games on improving English language skills , identifying different game genres, and elements and linking game elements with the four perspectives of game-based learning (GBL): affective, motivational, cognitive, and socio-cultural, highlighting their direct contribution to English language skills development. This study contributes to ongoing discussions on innovative pedagogical methods to meet learners' evolving needs in a technologically advanced educational landscape. The study provides valuable insights for policymakers, educators and researchers by highlighting the potential of commercial video games in enhancing English language learning.
