Educational

From Wikipedia:

Some people call these types of games edutainment because they combine education and entertainment. Closely related to the use of educational games is the use of what is known as Serious games. An educational computer game can be defined as an electronic medium with all the characteristics of a gaming environment that have intended educational outcomes targeted at specific groups of learners.

Video games can aid the development of proficiency by allowing users to interact with objects and manipulate variables. They are said to be particularly effective when designed to address a specific problem or teach a certain skill in curriculum subjects, where specific objectives can be stated and when deployed selectively within a context relevant to the learning activity and goal.

Simple types of games can be designed to address specific learning outcomes such as recall of factual content. For instance, the Nobel Prize Foundation website uses on-line games to aid children in understanding the discoveries made by its laureates by embedding the scientific knowledge as part of the game environment.

To aid in educating students and adults about the finer details of different political systems, numerous companies have developed simulations that immerse the player into different political systems by forcing them to make realistic political decisions. These games vary from running an actual election campaign to games that allow the player to make the day-to-day decisions of running a country, as seen in Democracy. These types of games are targeted at students, educators and adults alike.
