Serious games are games designed for purposes other than pure entertainment, such as education, health, public policy, science and corporate training. They provide collaborative learning experiences that engage and challenge users while developing skills. One example is America's Army, released in 2002 by the U.S. Army to provide recruitment and training insights. It has over 7 million registered users and averages 120,000 hours played daily. Serious games also require developers to transition from consumer-focused to business-focused models.
