A collaborative game at a distance
Not sure how it would support learning, don't know where artefacts might come into it, but certainly would encourage collaboration over distance!
Two players in different parts of the world, are connected by a mobile device. They must both reach a certain goal, set prior to starting, in their own locale - a coffee shop, park, etc...
The players must walk together....When one players turns, the other must turn too, or some equivalent....for example, both must reach the furthest left side of their previously chosen space at the same time in order to "unlock" doors and continue in another direction. So a route must be found, or movements must be made that work with the environments of both players. Much easier in a wide open space...much more difficult in an urban setting......
