(It's a long read but it's worth it.)
Galactic Civilizations 2: Dread Lords is a great Game. If the following concepts are included in Galactic Civilizations, without it being too complex for the player, then it would become a near perfect game... In my humble opinion.
I know that some of these concepts have been mentioned and debated. I'm trying to use "influence" on Stardock. Hence my subtitle: "Any Ideas? Let's inform Stardock."
-researching and constructing Ringworlds

and Dyson Spheres (or Dyson Shell, or Sphereworlds).

(see the 'Ringworld' novels by Larry Niven) A Ringworld is an artifact constructed using a systems planets and asteroids to form a ring around the sun. The inner surface is used like a planet. "Shadow Squares" provide day and night cycles and solar power.
(see 'A Hole in Space': "Bigger Than Worlds" by Larry Niven) A Dyson Sphere (or Dyson Shell,or Sphereworld) is the final costruction phase of a Ringworld. It is the ultimate engineering project of a civilization. A total sphere around a sun. The inner surface (and in some variants the outer surface; maybe both) is used like a planet. An artifact to be feared and revered for its potential.
-researching and using terraforming. Planet atmosphere/environment to match different races. Terraforming would alter a planet to a specific type for races and improve planet class. There could be slowly decreasing pennalties as the terraforming progresses. The pennalties would be due to the different atmosphere/environment. The atmosphere/environment for your race would be chosen during race creation.
-researching the ability to destroy planets and use the resulting asteroid belt to contruct a new planet again...and again...(This would require technology close to being able to construct a Ringworld.) This should be a device of a certain size to fit onto hulls.
-researching the ability to destroy a star ,and thus its planets, and use the resulting gas and debris to construct a new solar system with a Ringword again...and again....(This would require technology close to the level of constructing a Sphereworld.)This should be a device of a certain size to fit onto hulls.
-more civilizations per game; larger maps/galaxies; more races that are less humanoid; higher maximum number of planets per solar sytem: ten is a decent number.
-endless research: in later tech tree each "breakthrough" would lead to pluses to various categories such as military, diplomacy, happiness, industry, etc. Science Victory could be reaching a chosen amount above top rival(such as 3,5,or 10 times more advanced).
-multiple paths of simultaneous research possibbly using funding sliders.
-ability to construct on/at a planet more than one ship, building, etc. simultaneously; possibly using funding sliders at each planet.
-a seperate tax rate for each planet using sliders at each planet. This would be like state tax while the overall tax slider is like federal tax.
-better proportions: solar systems "tucked" into one "square/space".You could then enlarge the "System View" where there are system "squares" for exploration, travel, ...and battle.
-expansion into multiple galaxies: via "regular " drives wich would take... a long time; and later something quicker like a gate or special warp/teleport.
-the in game,each battle,option of player control over battles...space and ground(though the ground part might need some redesigning).
-orbital bombardment of planets using any/all ships and weapons:beams,missiles,cannons,etc.There would be varrying degrees of dammage to the planets infrustructure,population,and morale based on the total ships attack value.
-planetary defenses such as missle bases, beam bases, fighter bases, orbital platforms, and planetary shields.
-an Evolution / Civilization / Galactic Civilizations hybrid like the upcoming early 2007 release of Spore.
