Majors joining Trade Leagues - gamey or not?

[Darkrenown]

Thanks I too found out in a vanilla test game. I was playing a mod so the option wouldn't show up even when I turned into a republic. Do you know which file the decision is located?

decisions/governments.txt:

	plutocratic_administration = {
		potential = {
			OR = {
				technology_group = western
				technology_group = eastern
				technology_group = ottoman
				technology_group = muslim
			}
			OR = {
				government = noble_republic
				government = administrative_republic
				government = republican_dictatorship
				tag = HSA
				tag = GEN
				tag = VEN
				
			}
		}
		allow =  {
			stability = 1
			placed_merchants = 25
			capital_scope = {
					cot = yes
				}
			war = no 
			is_subject = false
		}
	  effect = {
			government = merchant_republic
			stability = -2
			merchants = 5
		}
		ai_will_do = {
			factor = 1
			modifier = {
				factor = 0
				num_of_cities = 3
			}
		}
	}
