Yes, it does for the most part. Leaning good or evil does have other issues tied to it other then getting cool techs. In general you'll have worse relations with the opposite civs. One thing you might find is if you are Evil that the Altarans or Torians might just declare war on you to "cleanse" the galaxy of your evil and for not other reason. If you are good the Drengin or Yor will constantly pick on you in the same way.Originally posted by Solver
So I assume the Good vs. Evil thing in GalCiv2 can work sort of like religious blocs in Civ4?
So yes, civ relations have a lot to do with your alignment. So for example if I have a lot of good civs around me then it makes me think twice about taking the evil choice with random events, assuming I don't want to war with them early on.
