Continent Plus，all standard setting. I'm Korea with Shaka on my south, Polynesis on my southwest and Sweden far northwest. Shaka's and my capital is a bit close, so after he builds his 2nd city in my direction my capital becomes frontline inevitably. I immediatly know a war will come soon, so I research contruction and build CB, covered with spearman(no iron near my capital). But Shaka's science is so fast that he reach education even before I have Civil Service. Now he already had swordman, capatult and Impis are coming before too long. What should I do?
