In Sights

From the introduction:

We’ll play secret agents with telepathy, spying. We chase each other all over the world, through cities and ruins and wilderness. At first we get to say what our target does as we watch them from afar. As the game progresses our interaction with our target becomes more and more intimate, and they have more and more say over what their character does. Sometimes we’ll fall into a romance with one another, sometimes a heated rivalry, sometimes we’ll manage to see into each other’s minds, and sometimes other orders divert us for a time, always with the pressure from our superiors to terminate the target if they become a threat.
