Tried it on standard size, quick speed, Hellblazers Pangea map as Japan. Had a monopoly on whales, and the most land in the game at 6 cities. Shaka warred me out of nowhere from across the map, and as I was fending him off, 3 other neighbors declared war on me the same turn. I tried to pay them off to fight each other numerous times, but it's always Impossible! I had 6-7 defense units in my forward city, but was overwhelmed by superior tech. Should I invest heavily into military early game, neglecting infrastructure? I was at bottom army, so even though I had personal defense, 3 civs combining to bone me would seem easy to them. I went Progress, which I assumed to be the strongest of the 3 openers.
