Digital street game seems to reflect the philosophy initially behind MapTribe:

By using a game as an open-ended platform for research we hope to encourage creative expression and collaborative play. As part of the game, players generate documentation and commentary that traces their paths through the game – and the city. Different views of these traces create a prismatic portrait of urban places as mediated through technology use and social relationships. The game becomes a methodological experiment in producing a rich environment for community engagement and social research.
