Economy

Upgrading economy increases your daily income. For each point of economy you have on a star, you will earn an extra $10 per day.

When a star is captured, the Economy of the star is destroyed. The conqueror receives $10 for each point destroyed.

Industry, Science and Warpgates are unaffected.
