Dev Team -
I'm hopingyou will improve the poor example of trade and economics in Galciv 1.
One of my biggest beefs is that you had a fixed number of trade routes. Now on the surface - I like the idea - civilizations becase of culture concerns would naturally would want to control the number of "foreign imports" to their civilization. However - this should change if your relationship changes with that civilization. In addition, if you conqueor another civilization - your trading should just become domestic trade routes - not stop all together (example - in Galciv 1 - if you have 6 trade routes - with 2 civlizations (2 apiece) - if you conquered one of those civlizations - you actually got punished and your maximum trade routes went down to 3.)
So to sum up -
1. Trade routes should not go away becasue you conqueor a planet or civlization - they should just become domestic.
2. Closer relationships with an civlization (such as an alliance) should bring more trade routes
3. Trade routes should be allowed to be set up within an empire to increase one's own economy.
