Not sure about accurate analysis but it is more about playing style. Note that Neutral is also a perfectly legitimate choice.In other words, are there any real down sides to being Evil? Since Evil gets all the good stuff in all those ethical dilemmas I have seen so far.
Being Good will give you 25% bonus on trade with good races and also a diplomatic bonus with them. You'll get defensive components and technologies. Hall of Empathy you can build has a nice effect (doubles the chance that a race will surrender to you although tricky to use). The advantages work best if good races are strong in your game, otherwise the trade and diplo bonuses are wasted. As I said, I rarely go good unless the good races are also strong.
Evil is great. They are freed of starbase upgrade costs and can build the No Mercy Invasion Center which will eliminate cost of special invasions. Throw in special weapons and this is the conqueror's choice. Note that United Planets may come up with a resultion to decrease your trade routes.
Neutral will make your upgradeable tiles instantly available (a big bonus). Your citizens are more content, you get a bonus for instant buying of ships and you can get Neutrality Learning Center which are the most effective research buildings in the game. They can research Neutral shipping for more trade routes, they get a bonus in ground fights versus other alignments. Neutral is my builder's choice.
I think it should apply only to the planet you've found it like the other random events.Originally posted by Urban Ranger
By the way, does anybody know what a "starship bounus is" (something you get if you deal with the pirates...)? Does that apply to all my ships or just ships built on that planet?
