This is a highly addictive city builder. It is also the most realistic of this genre I have played(and I've played a lot of them). The object is to build up the city to over 400 people(4th tier) and fight off raiders periodically. Keeping your people fed and happy is challenging yet satisfying. Through farming and herding you supplement your food production of hunters and gatherers.
You start out with 10 people and some supplies in the wilderness. Through careful nurturing ,you build homes and businesses, start trading for needed supplies, and mine for needed resources. There are easy scenarios and tough ones to play through staring with fewer resources or more, better starting conditions or more harsh. You can select more raiders or less(or none) depending on your skill level.
My only negative with the game is that there is no end point to claim a win. It is open ended and you can build until you are tired of expanding. My current city is now over 700 people and I have read some accounts of well over 1,000. It would be nice to say I won!!!! But overall, terrific experience for city builder lovers....

Simple pleasure

Good game so far, hope they keep working on it
