It is a very simple straight forward game.
There are 4 colors of cubes. They are a form of currency. They can be upgrade and traded to gain better ones that will let you acquire better people and buildings.
The top row of cards are people that you can assign jobs to. You will pay for them up front and then they are free to play from your hand. They will give you a 1 time effect but be worth VP at the end of the game.
