Watched the first two, nice in depth for people new to the series.
Quick tip: When you're looking for a place to settle (as in video 2), PLEASE click the button on the top right. You know, the one just to the left of the tile yield. It has the same effect as hovering over the settle button, but stays on and doesn't require your sovereign to be selected. I kept trying to click on the button while watching the video, I wanted to see the tile yields. Makes looking at potential settling sites much easier.
