Galactic Civilizations 2:Dread Lords is a great Game.If the following concepts are included in the next expansion then it would become a near perfect game...In my humble opinion.
-researching and constructing Ringworlds and Sphereworlds.
-researching and using Terraforming.
-more civilizations per game;larger maps/galaxies;more races that are less humanoid;
-planet atmosphere/environment to match different races(terraforming would alter a planet to a specific type and improve planet class).
-Endless research:each "breakthrough" would lead to pluses to various categories such as military,diplomacy,happiness,industry,etc.
-better proportions:solar systems "tucked" into one "square/space".You could then enlarge the "System View" where there are system "squares" for travel...and battle.
-expansion into multiple galaxies:via "regular " drives wich would take... a long time;and something quicker like a gate or special warp/teleport.
To make this list complete...though it's been mentioned and I believe being developed:
-the in game,each battle,option of player control over battles...space and ground(though the ground part might need some redesigning)
-scitech
