Perhaps a silly idea, but how cool would it be if the current effects given to realms effected by the ice/monster invasion, where given to every realm in the game with a fairly extreme player density.
Those rare situations where a realm is so crowded that tax shares are so low only a few can pay for a unit, for example after being seriously reduced in size after a war or something else.
These effects will give that realm a boost to be able to for example migrate to the together side of the map or simply start a war against their a little bigger neighbor.
Why? because we normally see these realms just slowly bleed out noble for noble, without any realistic chance for conflict.
Its like a last chance for potential, small realms to not only survive, but to remain fun and grow.
Perhaps equally, the opposite effect could be given to realms with an extremely low noble density, slowly increase their unit costs, more morale penalties for marching away to far.
This will force bigger realms with low noble counts to fight wars only with direct neighbors or just reduce in size, preferably both.
Preventing big realms to become police realms of the continent, marching anywhere to include them selves in every conflict.
I understand there are already other mechanisms in place, but i really see potential in this effect on the game in general.
