I ask because a friend and I played the game in person, and it was a bit confusing to see 1 square = 15 inches. It was almost half the size of the table we used.
It was also strange to see some units that had a size of 2 squares. It makes sense in roll 20, but when one square = 15 inches, that means the figure you need sounds like it has to be 30 inches by 30 inches. Which is very large.
We ended up making 1 square = 7.5 inches, this was very big, but playable.
