Ok, I played my first game just a few minutes ago and I came away with 2 unanswered questions...
First, on the Empire side of the screen, my communities have a series of red and blue boxes next to them. I am guessing red is bad (a shortage of some type) while blue is good (a surplus of some sort, perhaps). Anyhow, what do they represent?
I also never got around to casting a strategic spell, largely because I was low on mana. That aside, it was not clear to me how I would have casted a strategic spell. How do you do that?
