This is basically a simplified Settlers game. Each level is a different map with different goals. You get slots on the map, but some of them are hidden until you build buildings close enough to reveal them. You have to build defensive, economic and population increasing structures in order to reach your goal. Depending on how fast you do this, you get a medal. I have managed to get a gold medal on every level as well as unlock all the achievements in the game in basically one go, so the game really isn’t that hard. Still, it was fun while it lasted.
