1. Culture increase friendly allegiances and lower the opponement ones until they get to 0 (They become neutral). Building more Broadcast Centres will enchance the rate of spreading and its power.

3. Building more rafinery do not improve the rate of extraction.

4. Long range jump is useless in single star maps. Wormhole navigation is useless when their no wormhole

Some corrections to Harvatos' answers.
I believe it improves the spread rate (and the ability to spread into systems where capital ships are present), but culture is an "all-or-nothing" switch with respect to power. Either you get the bonuses and allegiance change caused by your culture being present or you don't. You don't double-up on, say, the Advent shield mitigation bonus whether you have two or twenty broadcast centres close.

You can increase culture bonuses by researching the spread rate - each improves that race's specific bonus a bit. This has been posted several times in other threads about culture. Have a look around the Sins and Strategy forums for more info.

Having more orbital refineries DOES improve the rate of extraction, but only up to a ceiling. If you look at the infocard for any extractor, you'll see it has a number of refineries that it can support (before you build refineries, it'll be "0 of 3 refineries" for asteroids that are next to a planet, and "0 of 4 refineries" if in an empty gravwell). That's the maximum number of refineries that'll get a bonus to resource harvesting from that specific asteroid in an adjacent gravwell. So, for example, if you have four refineries in adjacent gravwells to a planet with three crystal asteroids, only three of the refineries will increase your overall harvest rate from those asteroids by sending refinery ships to them.

Thanks for the info everyone. I've got a couple other questions:

Regarding Artifacts, how often do you find them? Are they more frequent in larger maps than smaller ones, or is it only specific maps that have them? And is their location random or always on the same planet?

My other question is about the AI. What's the difference between the different types of AI (Economist, Aggressor, etc)?

Thanks again!

I looked an dozen of maps and here my conclusion: all maps have the defaults rate of artifacts (15%) and of planetary bonus (40%). Hope its enlight you!


I forget researchist! An AI with this type will focus on upgrading and having high tiers units.

2. The allegiance is based on how many phase jumps away a planet is from your capital, which is stated in a box at the bottom of the UI. You can increase your planets' allegiance by spreading your culture to the planet. However, this only helps to a certain degree.

I already had my home planet with an allegiance of 120% LOL!
