Currency are as good as Corporation - almost

~250 gold worth ~1 turn but Washington is too far from Delhi so no way to expand 1 turn faster.
4000 BC W W
3900 BC N, settle
3700 BC galley from barbs
3600 BC buy BW, sell Democracy (3500 sell Demo to Aztecs and block production, they will have 1 Pikemen to 2300 BC or later)
3400 BC buy IW, take Rome + CoL
2700 BC Delhi
2600 BC Tenochtitlan
2500 BC Republic (i should switch earlier - more hammers banked), 100g settlers
2400 BC Medieval Era, 7cog (250g)
2300 BC Literacy from hut
1600 BC Banking from 250g, Ind+Corp from huts
1500 BC Democracy, ~40 cities, AoC
1000 BC Iron Mine
900 (or 1000?) BC last GP from temples, GB+GS from SoC, Oxford rushed
700 BC GS for Communism, 6 wonders rushed (later 21/20 cultural milestones)
400 BC Cultural V (i can see 400 BC without GB)
{for Dom: 2300 BC Washington (18 vs 21) and Tenochtitlan (18 vs 10.5?), 1 turn earlier is possible}
Aztec walk in looks better (than Roman walk in) but isn't. Walk in 1 turn earlier, 2 cities should rush 2 LA 2 turns earlier - 3 turns advantage (it's reason why i ignored Roman walk in at start). But: 1st upgrade useless Medic, lack of gold, worse seed - 3 turns wasted, after that lack of gold - next 3 turns wasted.
