To start your kingdom off good, your gunna want to first: get a volley (a back and forth hire between players) when you get about 50 million gold then explore 9 lands and build forges. upgrade your forges to level 3 before you build a new one join a good clan that does epic battles be active in epic battles to gain a lot of gold. when u have enough, start building subterranian factories. keep building those and DONT FORGET TO BUY ALLIES!
As much as I like your guide, I'm a bit biased and believe this is a better method to start your kingdom off on a good note, if a bit outdated.
