bigger penalties.Any invention is a "gamechanger", smaller or bigger in field of medicine, agriculture, warfare or politics
high wals are obstolete in rennesaince era - too slim, too easy-crush for bombards and later canons, when compared to star forts
High Walls:
defense from 50% goes down to 25%
damage from bombardment from -40% goes down to -20% (cannons are walls-destroyers compared to trebuchets and catapults)
Star Fort (and Bunker)
defense from 25% goes up to 50%
damage from bombardment from -20% goes up to -40%
star fort its technically just thicker and more stronger version of castle, high wall.
remember in renessaince era people go from long-term sieges to quick assault on fortress after crushing the walls
its a time when calvary first time in history was equal to power with mans who carry weapons (muskets)
later when rifles was invent, they lose even more and heavy - calvary was replaced by quick units with 3
to make skirmishes on enemy lands. or to simple reconaissance
i think AI will be like this idea
Also i love idea from realism invictus where when you build united nations you can vote on ANY doctrine, not only secular, green, democracy etc but i belive its too complicate to rewrite a new dawn in this way for now
better just fix actual bugs and later concantrate on this, if you want ofc
like:
Ai should not attack civ with who have +10 to attlite (or simpler: like them)
exept these with spy points perk, they are always a vipers
ai should not attack enemy civ who have bigger manpower (like india or japan who was weaker , much weaker like 50% of my strenght and declare war on me)
and most important:
ai should never attack civ with nuclear warheads if dont have their own warheads.
exaple ? Israel. Surronded by countries who likely want destroy them
also in modern era we too dont have any evidence or examples when country without nukes attack country with nukes
countires become more careful in modern era if we talk about declaring a war - they can gain little and lose too many
