So once again if we look at this from various perspectives (as with the Solovei razboynik tile), I think the most probable answer is no - for being feature, and yes - for wagon movement.
Let me elaborate:
Bogatyr stone lacks certain attributes which define a feature: (1) it cannot be claimed, (2) it does not have a special function or effect.
So while it does have unique art, it is mechanistically indistinguishable from a normal crossroad. So we can assume it works exactly like one.
From thematic perspective, we know that the stone reads:
Go to the left, and you will find death
Go to the right, and you will lose your horse
Go straight, and you will lose yourself
Implying that the Bogatyr on the horse can indeed pass the stone and travel straight.
It should be noted that this is the only tile out of the 4 russian promos that does not have any special effects, only unique layout. Some might argue that it is a feature of its own since it has a name, but the names of the russian promos desribe both the feature and
the tile itself . So in this case, I think it is just the name of the tile.
I will check if I can find the original tale this tile is based on and search for further clues. All in all, an official statement from HobbyWorld would be appreciated (Murphy013?
).
