Soil Enhancement and Habitual Improvement! - I've read about the following somewhere here:
Turn 1: Set Taxes as high as possible, Set Spending at 100%, Set Social Spending at 100% the others on 0%. On Earth *build* Soil Enhancement, and *buy* a second colony ship.
Turn 2: Found second colony if possible, begin to build Soil Enhancement. If you can't, don't do it (obviously).
Turn 3: Soil Enhancement on Earth is finished. Reduce Social Spending to 0%, Research at 100%. Research Medical Theory and Basic Environement Control.
Turn 4-8: Build thierd colony.
Turn 9: Basic Environemet Control researched. Put Social Spending at Max and start building Habitat Improvement on Earth and Soil Enhancement on the two colonies.
Turn 11: Begin to build Habitat Improvement on the two Colonies.
Turn 13: Begin to build Aphrodisiac on Earth
Turn 15: Rush Build Aphrodisiac.
You'll end up with 3 prospering star systems, a trade good and ~147 bc minus (depends on the quality of earth). Reduce spending to 40% and put 100% into research of Universal Translator.
