The reason is that it becomes difficult for engine to find place for all hedgehogs on small maps

I see... but on large maps there isn't that problem...
You see... if I play with 4 players then count of hedgehog for each player is very few...
That's why the maps should be generated (or scale) rightly for number of players (hedgehogs).

4 hedgehogs for everyone is enough, isn't it? What would you like to do with 30 hedgehogs staying on top of each other!?

:P
6 for everyone is enough on large map

I agree that...
If there are 2 Teams, you can play with 8 hedgehogs each. If with 3 teams, for being fair you can put 6 for each...
This is way enough...
