Does anyone know is star control like galactic civilizations please list the differences and the similarities.
There are three Star Control games. I guess the closest to Galactic Civilizations would be Star Control 3, since that had colony management. Or Star Control 1, which didn't have a adventure mode. Story wise, there two specific similarities, the planetary shield idea and in GalCiv 2: Dark Avatar, Drengin = Druuge/Ur-Quan Kzer-Za, Korath = Ur-Quan Kohr-Ah. Star Control Wiki
Pff, Original ideas? That is a writer's job.
