Now I have called this strategy a tournament indusrteialist strategy becuase of the simple fact that in the tournment game you cannot change your government more than once. This strategy starts out with the best government so it does not require that you change it, however this is also a very good strategy for any other earth game.
Strat 1 - Tournament Industralist Strategy
build 8 Construction sites(CS's) (8 turns)
build 18 industrial sites (2 turns)
build 9 industrial sites (1 turn)
sell spies (in purchase menu)
build 4 CS (4 turns)
build 8 CS (8 turns)
sell spies
build 36 industrial sites (3 turns)
build 8 CS sites (8 turns)
build 8 CS (8 turns)
sell spies
explore (5 turns)
build 72 industrial sites (4 turns)
build 18 farms (1 turn)
sell spies
build 18 industrial sites (1 turn)
explore (5 turns)
this takes you to about turn 50 or so... change production to 70% turrets and 30% spies. Continue to explore for 5 turns and then build untill that land is gone, selling spies when you need the cash. at turn 85-90 change production to 90% turrets and 10% spies... this will give you plenty of turrets coming out of protection and will also allow you to sell one third of them at the end of the day to have cash around... allowing you to keep your spies from this point on.
