Just started playing the game last week - loads of fun, but also loads of questions.

Regarding the use of Economic Starbases and the benefit gained from trade routes passing within the Starbase's zone, is it cumulative? In other words, if I've 5 trade routes from Earth to other plants, how can I maximize the revenue? Could I have a string of Starbases along the routes, all creating additional income?

Never mind - just read some previous post re Starbases - much clearer now.
