Geo-gaming is a crossover between gaming elements and location, usually enabled by location based services and augmented adn/or virtual reality features. Geo-games, also known as “location-based games” or “location-aware games”, have geodata at its core, since geoinformation constitutes the central element of the game mechanics. Geo-gaming applications present unique technical challenges to meet the infrastructural and resources demands from the games and location worlds. There are mainly four different types of geo-games: exploration games (to make use of an existing spatial design); feedback games (to report about players’ experiences in a specific design); allocation games (to occupy the majority of game location); and configuration games (to occupy specific pattern of game locations). Gamers actively participate by interacting with the environment, therefore gaming scenarios are as varied as their goals, which include teaching, training, and the developing of spatial thinking skills. Geo-games offer a myriad of opportunities to developers: non-linear storytelling, physical object integration, a more visceral experience, true social interaction… which bring geo-games to another interaction level. Geo-gaming applications often rely on VGI to allow gamers adding geolocated information that may crowdsource geo-referenced data useful for other secondary purposes .
