Nintendo's popular brain-building series returns with an emphasis on short-term memory and focus in Brain Age: Concentration Training. Working on the premise that a society full of emails, text messages, and video clips has produced an information overload, Concentration Training aims to improve working memory through a variety of five-minute exercises. Dr. Ryuta Kawashima returns to guide gamers through simple math problems, matching, and cup-and-ball mini-games, among other activities, and the game offers dynamic difficulty settings that adjust to players' progress.
