i have said this before but i just wanted to define it more. i think that to seal the game together would be trade. trade would be like certan territories have a exotic substance and trade would be like a land/sea trade also with said trade you could make a more important diplomacy rather thing just allinces like well playing this i was allies with a country for like 200 years give or take and then in 2 years of breaking up we went to war and i allyed to a hated countrie. p.s with trade would be a from of getting money and with money you would get more/better armies
