In this digital age, EFL students have been used to using technological media in their daily lives. They have learnt English through video games even before they meet their English teachers for the first time in primary school. By the time they are adults, they have learnt a lot because of video games. Video games are also believed to be able to enhance students’ 21st century skills. EFL teachers need to improvise the teaching and learning activities by inserting video games in their classrooms not only to improve their students’ English ability, but also to enhance the students’ 21st century skills needed for the upcoming Asean Economic Community (AEC) in 2015. From this perspective, this paper is aimed to discuss the integration of video games in EFL classrooms for adults by EFL teachers in institutions, the guidelines regarding the practical use of this technology, and the 21st century skills that can be enhanced through the use of this technology. This paper is useful for EFL teachers to utilise video games for learning and to motivate students.
