MobiMissions: the game of missions for mobile phones.

Mobimissions is a location-based pervasive social game in which players use camera phones with location-based capabilities to create, share and reply to real-world missions. Missions and their responses are defined by sequences of digital photographs and text annotations. Players create missions, search locations for available missions, create responses to and submit missions for others to find. They can visit a website to review and rate all missions and responses. Feedback from a trial involving 11 players over five weeks reveals patterns of play, preferred locations for play, the limitations of location-based play, and the need for greater social awareness and exchange. Future directions for such location-based social games are suggested.
