I'll get to the main question first: Is there any difference in the rate of culture accumulated while at war, vs. peace? Does mobilization make a difference in culture accumulation (I know it makes a difference in what your cities may build)?
Background: I was going for a 20k culture win (my first attempt at that victory condition), and not doing too badly -- regent difficulty. Bad news: I made some mistakes in my construction of wonders (not soon enough) and in city management (didn't build a factory in the 20k city, so it doesn't have enough shields to make the later wonders fast enough).
Good news: I had built enough cultural buildings across the rest of my empire, that a 100k victory was still possible. I used cash-rushing to build lots more cathedrals, and packed in some little towns which also got temples. I was (and am) number one in score and technology. Better news: number 2 decides to invade and thoroughly trash number 3, both located on the other continent.
Bad news: I realize that I've let number 2 grow too much culture of its own; over 50k, and approaching 60k. That means I'm going to have to over-produce culture, to get more than 2x the culture of the number 2 civ.
Good news: I am gaining culture at a *much* faster rate than number 2 is, so I should double them before time runs out. I hope
I'd win via histographic anyway.
Question: I've been building up my armies in my outpost cities on the other continent, and could invade the number 2 civ. It would be an epic war, with my goal of razing his high-culture cities. But if I slow down my own rate of culture accumulation by declaring, I'll risk losing the race and have to settle for histographic.
