Us immortals tend to find ways to fill the seemingly unlimited time we have. With the benefit of consistent focus across centuries, things that would be otherwise impossible become achievable. Cultivated erosion, stop motion bonsai, one person medieval tapestry, lots of potential ways to pass the centuries until the heat death of the universe.
But others instead find games to play. A bunch of us are playing one right now, a sort of hybrid of Risk, Diplomacy, and Civilisation. We call it "Socio-Economics", and how are you liking it so far? Not that it matters what playing pieces actually think...
