Hmmm... Stargates connecting most worlds, some without stargates... move populations and troops through, making for a more troop-centered game. Make starships harder to make, so there is less of them and space battles are more intense. Ancient technology has to be researched after finding it. Have to make troop transports to attack those worlds without stargates. Warp points would be generated by ships... larger ships would be able to warp farther than small ships. Warp points would then dissapear after being used. Lots and lots of neutral AI, ready to become subjugated
