Islanders is only a few bucks and very serene. You get a random island and a small palette of buildings at a time. The buildings can only go certain places (farm on a plain, quarry near stone, hunting lodge near forest). You get points for putting certain buildings together, or certain ones further apart (mostly in ways that make sense). And that’s about it. When you use up the buildings on your palette you get a new set. There’s no timer, just try to get points. When you reach the goal you can start over on a new island.

It’s very simple. You can’t move or demolish buildings, you don’t worry about roads or infrastructure of any kind, there’s no citizen happiness or disasters or money or anything. Just relax and place little buildings on islands.
