I lost my first game today. After learning some of the mechanics on my first playthrough I decided to fire up a small Pangaea domination game with Tomyris. I'm cruising through Civs and get to Ghandi on the other side of the map, I had to cap 2 cities to get to Delhi and as I capped Calcutta (the last city before his capital) the loss screen triggers. I never thought that Ghandi had basically the only religion in game and he won a religion victory. Gotta be more cognizant of that as I never got a warning during the game.
