Terra
with all the Liberty tree talk on the forums lately, I've been playing a couple of games as Spain/Huge/Terra. I rush Navigation and send 2 CB, 2 Horse Archers, 2 Horsemen, 2 Workers, A settler and a missionary or two to the new world. By the time they get there, you've researched Chivalry and can upgrade the 4 horse units to Conquistadors. Use those to clear barbs and help CSs then use them to settle more cities. With 5 cities in the old world, you can drop another 5 in the new world REAL QUICK making for a great liberty game. As Spain, you get first dibs on all the Natural Wonders... too good.
