If it is 500m then the Stalingrad scenario map seems really out of scale..Stalingrad was around over 45km's long from North to South (it's even longer now) so thats a fair few hexes in length. Look at the Stalingard map in my link above..thats roughly the scale it should be...
A shame..is it possible to create new maps?
SO as you can see the map is not just abit off scale but massively off scale. I think if the game can't support a map big enough then the battle could have been divided into three, North,Center and then South. Three separate scenarios. Also if you look at the city graphic tile it's also way off in scale.
If I had the talent I'd mod the hell out of the map graphics and create three scenarios.
Streets of Stalingrad is 300m hex..it's roughly from the furthest south upto Spartakovka 70 hexes, and anywhere from 13 to 4 hexes wide. This map was taken from aerial photos of the time so should be pretty accurate.
Better late than never, eh?
