1. You made them. At all. [;)]
It is apparently a easy mistake to make. And once you do, people will do math and start complaining how X, Y or Z can not add up with those measurements.
It also ties you down to having to match the Planets physical sizes to map sizes, wich means the mapsize affects gravity, wich in turn affects: atmosphere, seasons and biosphere.
2. Earth is supposed to be roughly 200 hexes
Earth has 6371.0 km Radius.
A large moon is 61x24=1462 Hexes
It clocked in at a 1974km Radius.
The values are off by a few orders of magnitude.[:D]
What the game seems to use:
For the moon (1462 Hexes, 1974km Radius) I get to 48967074 km² Surface area.
So each hex is roughly 33447 km²
Real World equivalent:
So 1 hex is roughly the size of Moldavia or Belgium
Netherland is about 1 and 1/3 hex, but landmass is only 1 Hex.
Germany wold clock in at 10-11 Hexes
Derive from earth 1:
Earth has a whole (water included) has a surface area of 510 072 000 km2
Wich gives me almost exactly 15.250 hexe.
If we go back from that and asume earth was used to get the "measure of a hex", I would put 1 Hex at:
33.447,344262295081967213114754098‬ km2
Derive from earth 2:
What if we want to split earth into a nice even number of hexes? Say 20000?
We would get 25503,6 km2 per hex.
Wich gives a edge lenght of 99 km
Long Diagonal of 198km (nice fitting that one 200km number)
Short diagonal of 171 km
Perimeter of 594 km
Incircle Radius of 85 km
And after actually reading the book properly:
And now I just realized the Manual only gave a rough Circumference in hexes. So basically dividing the circumference by the short or long diagonal? Unfortunately, that also does not add up:
40007.86 km / 200 = 40007.86 km of either the long or short diagonal (more likely the short).
Only 200 times as wide as indicated
