Thought I'd give Roosevelt a try at this. A 15 settler start, but lost one due to war. (My bad.) Four AIs bit the dust by turn 100 due to warrior rushes. Massive REX start but lots of cash on hand for expenses. A different path through tech and, comparing to my Darius game, tough to call. But the light is beginning to clear the darkness. It's 170 AD and Roosevelt appears to be breaking my previous attempt. He's up a solid 4-techs: democracy, radio, industrialism and plastics. Perhaps its a 10-15 turn improvement. It is also is fodder for improving play with Darius.
