Readers of my Newbie AAR will remember me asking about this at the beginning of the week; I thought it might be a good thing to branch the subject out into its own topic as I have a few more questions to add. I've been too busy to play for the last few days and that has allowed me to dream up new questions to complicate matters 
To quote the answer kindly supplied in the AAR thread:
How about expanding existing factories verses building new ones; if certain factories are worth more do they also give you more points when upgraded compared to other factories, i.e. is the increase based on a percentage of the factories score?
Do closed factories still give you points? Empty ones do, but what about ones that are shut down completely?
Are there any other factors that boost the industrial score?
Just how does your industrial score relate to your overall score anyway?
Anything else I should know?
To quote the answer kindly supplied in the AAR thread:
So, are all factories worth the same or do certain factories give you more points? I'd suspect the more expensive factories give you more...The Arch Mede said:To increase industrial score, keep building and expanding factories, particularly expand steel. Your industrial score will go up even if you don't have workers available to fill them. A level 30 steel factory with only a dozen workers in it gives an enormous quantity of industrial points. Also pay off loans.
