Agumented reality games involve adding additional information to an existing envrionment.
The citizen science movement leverages the community of the Internet to help solve real-world science mysteries in the form of puzzles and games.
The serious games, or social games, movement concerns the making of games that instruct and even assist with real world issues. These games are designed not to provide an escape from reality, but to immerse the user further into reality. These games can teach about a historical event, assist with actual scientific research, immerse a player in a real world problem, and even add a little gamification to everyday activities.
