Several researchers have found that video games, such as sports games and the well-known simulation game, "The Sims", can be useful for language learning. Some researchers also suggested the potential of adventure games in language acquisition; however, few studies have investigated the impact of adventure games on foreign language learning. This study aimed to examine the effects of a commercial adventure video game on foreign language learning. A group of 35 college EFL students in Taiwan were asked to play an adventure game "Bone". Students' perceptions toward this adventure game were investigated. The results showed that students considered the game helpful in improving their language skills and learning attitudes. Students also reported their enjoyment in game playing because of the game design. The findings in this study suggest that adventure games such as Bone can help college EFL students enhance their English language skills and learning motivation.
