I play gaia my worst civ, while playing this game with 1700+ and even 1750+ players.
Many strategies are used here.
My biggest mistake was that i did not do enough techs and forgot to set up a market early.
However my implode GP and the attack afterwards nearly crippled player red, if i would have pushed and had sent all mil. to his TC's i would have destroyed him.
A good game for all who want to learn to play norse, egypt,or greek.
