4000 BC (0) We are Japan. I move the settler to avoid wasting a bonus grassland tile. 3150 BC (17) A Nubian scout arrives from the north. Warrior code was insulted by, so they must be researching it. I give them sail and warrior code for pottery and $29. 3100 BC (18) Our scout finds a USA troop. We give them warrior code, pottery, sail for masonry, bronze working and $28. 3000 BC (20) We find another USA troop way south of us. Last find was to the east. Despite being near the map bottom I suspect USA may be below us.
