This is an interview study of Eldin, a 14-year-old Bosnian boy living in Sweden since the age of six. The aim is to investigate how Eldin became a gamer and how he, strongly motivated, learned foreign/second (L2) English mainly through self-access gameplay. Using language learning motivation theories, Dornyei's (2005, 2009) L2 Motivational Self System and Dweck's (2006) concept of mindsets, the questions are: (i) By whom and at what age was the learner introduced to video games?, (ii) What was it about the games that kept the learner motivated for two years before he started to play 'for real'?, and (iii) How does the learner himself describe his process of language learning? Data consist of an in-depth interview and three university-level vocabulary/multiple-choice tests measuring English proficiency. Guided by the questions, interview data were analyzed qualitatively. Eldin's mindset seems to favor naturalistic language learning, matching his interest in gaming. Experiences of having fun and daring to use 'trial-and-error' in gaming have contributed to his English proficiency, which is equivalent to a passing grade at second-semester university level. Elements of gaming (in particular, competition, stories, and escapism) appeal to Eldin, thereby indirectly contributing to his successful learning of English.
