Orbits is an AR game that has been slowly but surely gaining in popularity. Users of Orbits become the center of a small solar system, orbiting their head as if it were a star. They can manipulate events with their hands, sending asteroids and comets to and fro and shaping continents, or allow the simulation to take its own course. Life will arise on suitable planets and evolve quickly, eventually becoming intelligent tool users who will explore their solar system.
If other users are nearby, interstellar travel, first contact situations, diplomacy and war will occur between civilizations. Users sometimes congregate in public places to watch epic space-operas break out.
Orbits is an AR toy run on mesh inserts, so it should not come as a surprise that the simulation is no more detailed than the user requires. If the user is not paying attention, than the simulation is entirely statistical. If a user zooms in to watch an expedition to an alien planet, that expedition is detailed but nothing else. A popular extra for Orbits is an AI that monitors the activity of their planets and looks for patterns suitable for unique short stories, effectively a highlight reel.
