Research within the field of serious games shows that games and simulations can supplement traditional learning methods in a positive way. Modern technology allows for simulations of real situations thus allowing for improved vocabulary training. This paper focusses on ESL (English as a second language training) for adult learners and looks at how a prototype set of minigames could be used to enhance learning outcomes in a specific set of vocabulary. The paper looks at a case study carried out by the researcher in Plymouth in the UK at an ESL training centre. Results from this sample showed that this method of using games is viable, however not that much of an improvement on traditional methods.
