Found a funny S-map on gamerhome that takes about an hour to play. It's very easy, but with an interesting concept: you have to complete the map with just one peasant. Maybe someone will find it interesting. The map is in English.
I haven't played it myself, but the name sounds familiar: it's also in the collection of the best maps.
Here is a description in Russian and a link to the author's guide.
