That's what a critic would say.
Something along those lines.
I don't know about the respected Strannik, but I'll speak as a mapmaker with a lot of experience.
The map interface (landscape, nature, etc.) - let your imagination run wild, and that's it. If the map is empty and doesn't look interesting, I won't even want to play it.
Could you elaborate on changing the owner? I think you misunderstood a lot about this map.
Object properties (mines, etc.), assign a garrison ==> events ==> standard events ==> attacked ==> select the "script" tab. By default, it says "sequence," leave "sequence" at the bottom, and look for the "new" button. ==> change owner, select the enemy's color, and click "OK."
Study the scripts.
