The game looks cool. But why the map is diamond-shaped while the world is made out of hexagons? So many playable factions can be a bit too hard to balance and can be confusing for the player.
Interesting question about the map! It turns out if you take a regular square grid and convert the cells to hexagons, you end up with that isometric diamond shape. The internal representation of the map is technically a regular 2-dimensional array (i.e. a square with (x,y) coordinates,) and what makes it into a hex grid is a matter of what cells are considered "adjacent."
