A cursory Wikipedia search would yield an explanation:

"A serious game or applied game is a game designed for a primary purpose other than pure entertainment. The 'serious' adjective is generally prepended to refer to products used by industries like defense, education, scientific exploration, health care, emergency management, city planning, engineering, and politics."
