Defineately agree.
I would also like to see leaders 9ie Governors, Regents, whatever) and government types that influended how different things happened. A Feudalist government might be better at warfare, with a hereditary military tradition, but poor at growth, with an inflexible chain of command and people that were afraid of acting without higher support.
Leaders would be both system and planetary, they would affect the system or planet's output (mining, production, taxes, etc) They could have both positive and negative influences, removing a leader might result in a revolt by that planet, or even the system. Other nations might try to bribe a leader to revolt. If you don't have a leader however, a planet's moral will steadilly decline. Some leaders might be corrupt and leach a bit off the top, pirates might form readilly in such systems (more than one pirate world) and so on.
