So i was looking for a way to switch to a horde as Ryukyu and still get the achievement, because hordes are overpowered especially since rights of man, where you dont even have to reform anymore.I went to check the achievemnet conditions in the files, i noticed that the lazy guy who made the achievement just copypasted the World Conqueror achievement and changed some values. The 3M achievement doesnt specify that YOU have to be Ryukyu.Then i started a new Ryukyu game and conquered Jianzhou and switched to them with create vassal, because Hordes are overpowered i just easypeasy conquered the world, in the end i had no Colonies and my only vassal was Ryukyu who had some colonies. Because now everyone is a subject of Ryukyu, you get the achievement(or the ai actually). Not sure why it didnt count me in the check, since i'm not a subject of Ryukyu.Only ryukyu is my vassal:Small AAR of the campaign for those who are interestedEDIT 02.03.2017As we figured out how this works here is the summary of why/howany_country does not include the trigger and in case of achievements the trigger is always the player country.The World Conqueror works, because it checks for subject of ROOT (the player), though the OR tag = ROOT is unnecessary and doesnt do anything.In case of The TTM achievement, it checks for any country (except player) that exists and is either RYU or subject of RYU.That means, you can switch to any tag, since it wont check for the player country. Then you can either keep RYU alive or make all countries non-existent.There are 3 different ways of doing this achievement:1. You just do it regular while staying as RYU2. Switch to any tag and keep RYU alive, dont get CNs (RYU-CNs are ok)3. Switch to any tag and do a full one tag(no CNs)To not spawn CNs, you can either leave the colonial area uncored OR un-state everything and move capital to the americas.
