So, being completly bored and having a lot of time I've created an event that grants us an accepted culture after being in possession of 50/60 % of provinces of one type of culture. Here is an example of acceptance of baltic culture, where we'll have to own 4 of 5 baltic provinces for x years, and have stability at level 3 and not being at war. Feel free to comment and give some feedback.
Code:
event = {
id = 89002
trigger = {
someof = {
number = 4
ownerchange = { province = 283 years = 45 }
ownerchange = { province = 284 years = 55 }
ownerchange = { province = 288 years = 45 }
ownerchange = { province = 289 years = 55 }
ownerchange = { province = 290 years = 60 }
}
someof = {
number = 4
owned = { province = 283 data = -1 }
owned = { province = 284 data = -1 }
owned = { province = 288 data = -1 }
owned = { province = 289 data = -1 }
owned = { province = 290 data = -1 }
}
atwar = no
stability = 3
}
random = no
