Thanks! I'm sorry if I resurrected something that's been asked a million times
No probs. It's tough to find stuff if you don't already know about it. We used to have a decent search function on-site but what we have now is almost useless. The best is probably to go to google and use the site search function by including site:forums.galciv2.com in the search line. If you go to the advanced search it's included as an option.
The whole topic of scoring is rather large and there's always subtle nuances that could use further discussion but the above threads probably most of what you're looking for. Feel free to ask if you have additional questions.
