In Agricola, you're a farmer in a wooden shack with your spouse and little else. On a turn, you get to take only two actions, one for you and one for the spouse, from all the possibilities you'll find on a farm: collecting clay, wood, or stone; building fences; and so on.
You might think about having kids in order to get more work accomplished, but first you need to expand your house. And what are you going to feed all the little rugrats?
Agricola is a fine balancing act between expansion and keeping your family fed. Sometimes you will need to make hard decisions for a greater payoff at the end.
The family edition is a cut down standalone version without the occupations and upgrades, simplified to play quicker so it is suitable for ages 8+.
