KingLear
This isn’t a terrible idea. Kingdom achievements like “Build a certain number of houses and gain 1000 gold.”
It could also be used to guide newer players towards playing a basic “beginner” build by setting the achievement goals in that manner.
Other advanced achievements include having 7:1 schools at any point, gaining X, building 100 buildings in a single tick, or killing 25,000 peasants with a fireball, just to throw a few random ones out there. .
The bonus we used to receive daily was quite nice. It involved a quick ad, and in exchange, we received a bonus of gold, wood, iron, and food based on the strength of our kingdom. I used to click it just before the last tick of the 24-hour period to maximize the bonus.
