Hi,
I think everybody knows, that games like GalCiv make very fun at the beginning and at the end the empire is so big (much planets/citys) that it is no fun to manage all planets good. Most time, in a big empire the small/bad planets will managed not very carefully.
Idea:
If the empire is really big (many planets) you can choose in the planet-production-queue of a small planet a friendly bigger planet which you want to support. How good the smaller planet supports the bigger planet depends on the distance. Now, the smaller planets helps the bigger/better planet to produce faster.
...the production-support-route could be implemente like the trade-routes in GalCivII. In this case other factions could block the production-route with their ships.
I would like this feature very much and I think its not to hard to implement.
Greetings
