Though Olympics-mania has now left us behind, it occurred to me there's some potential in the idea of including the Modern Olympics in the game. Perhaps it could be reflected as a comparitively cheap Project: Modern Olympic Games +6 Happiness while Civilization is not at war. It's a useful little bonus and available for all civs. If we wanted to get more complicated, perhaps the bonus could start lower and be increased for every Civ that builds it. Or maybe it could grant bonuses for every citystate in the world?
