The game is great and offers a lot of replayability. The difficulty can be scaled between more than two dozen levels so regardless of whether you want a chill experience or be challenged, you will find something.
It is not a traditional city builder though. You will build several settlements and the goal is more or less to complete them as fast as possible and then move on to the next one. You will not get to the point where you sit back and just watch everything run like a clockwork because before that happens you will have won and moved on to the next settlement.
