Heroes VII

Where can you move across the battlefield in a single turn if the battlefields are of different sizes? Sometimes, there are as many as 20 cells between the starting positions of the opponents.

We're talking about comparing it to the fifth game, where there were many creatures with speeds of 7-8, capable of moving across the battlefield in a single turn. To fix this, subsequent installments significantly reduced the number of such units, but they didn't add more low-speed units; moreover, even units with a speed of 4 became rare. As a result, we got a uniformity of speeds of 5-6.

And regarding battlefields of different sizes – is this just a quirk, or does it not happen in multiplayer?
