I posted some thoughts on this in the starbase discussion but decided a seperate discussion would be good.
Is trade going to be revamped in CG2?
The issues I have with trade in CG1 are
   - all trade routes are between the same planets for maximum income
   - limit on number of trade routes 
   - there is no 'competing' with the AI to become a trading power
What I would like to see is these three issues addressed WITHOUT serious micromanagement. Not an easy task. 
Any suggestions?
