I've played this game for a while, and so far I play on regent and can do pretty well up until the industrial age. During the ancient and medieval age, I am almost always a tech leader, or close to being one, I have a good amount of gold, and I have the largest population. My problem is when I hit the industrial age and key resources appear: like coal, oil aluminum. Most time I don't get these key resources in my empire, and there are too few of these resources within the borders of countries willing to trade with me. How do I get these key resources? Do I declare war and risk angering every AI, or do I sit and wait with an outdated military until I someone is willing to trade with me?
BTW, in my games I usually invade, but sooner or later, every AI is annoyed with me and they begin to declare war on me like crazy.
