Victory conditions
From the Galactic Civilizations Wiki
Victory conditions can be set at the galaxy setup screen.
There are four ways in which you can win in Galactic Civilizations II:
- Conquest Victory: Wipe out all other major races in order to achieve this. Note that you can achieve this victory without conquering any of the minor races, even if they happen to control more than one planet. (However, since you are already in the warring mood, why leave them alone?)
- Diplomatic Victory: Form an alliance with all surviving major races in order to win this victory. This is a lot harder than it sounds, as some races will most likely never ally with you simply because of who you are. Unfortunately, some races really don't understand what it means to be friendly with everyone so you'll have to "bring them some friendship" in the form of warships and troop transports.
- Influence Victory: Have your civilization's influence dominate at least 75% of the galaxy. When you accomplish this task a message will appear, stating that if you maintain your influence dominance for 10 weeks you will win. You'll need to make room for a fair amount of cultural improvements and projects to get this accomplished. In addition, you cannot be at war with any of the other major races before this victory is possible.
- Technological Victory: There are five technologies at the very far-end of the tech tree that must be researched before being able to win the Technology Victory:
Some of the scenarios and campaign missions may have alternate victory conditions.
NOTE: It is generally considered to be a score multiplier of 1.0 for a Tech Victory, 1.2 for an Alliance (Diplomatic) Victory, 1.4 for an Influence (Cultural) Victory, and 2.0 for a Conquest (Military) Victory. This may be of interest to Metaverse players. Source: GalCiv Forum Thread
