Does anyone know of a game (board or otherwise) that uses non-regular hexagons? It seems like it could be a sort of neat way to represent bottlenecks, for example in a strategic game. (You could of course make the hexes smaller and represent a bottleneck by making some of them impassable… but then things might get more tactical I guess).
Because hexagons don't neatly stack the way that squares do, using different sizes (an irregular grid of regular hexagons) doesn't work as neatly as it can with squares. If you are using actual irregular polygons, I don't think there is much value to using any particular number of sides, you might as well just use a map with arbitrarily-drawn divisions.
