A lot of mistakes
I am giving one star because my son loves the map.  There are some very gross mistakes in the instructions.  I couldn't try to build the map on the floor to begin with, as my son was destroying it.  I did it right on the wall.  For size XL, the distance for marks is 250 cm, but this is a lot.  I had to peel off parts of the map and select the correct distance.  I ruined the paint on the wall and I was very upset.  The second big mistake is that the map doesn't have a few pieces.  The sakhalin peninsula was roughly broken off and was not in the box.  I paid $299 for the card then, and now I could buy it for $229.  it is unpleasant.  My son loves this card and I did not return it.
