i was bored of vanilla. Then i think about making a mod for myself to create some new stuff like new country, rebalancing or new idea set/policies. So i did this. And i played this like 3 times. It was enjoyable for me. I think you will enjoy it too. The mod will not change anything except adding new idea group, policies, events.
The mod adds a new idea group that you can pick it from "ideas" section.
It gives fire and shock damage bonus because there is no such idea group that gives these bonuses.
Localisation texts of new idea group's ideas have reasonable arguments.
Mod adds 10 new policies for new idea combining with other idea groups.
Policies have pretty good bonuses.
Mod adds 9 new event. To trigger new events you need to have picked Power Ideas. Don't forget it has a low chance to happen every 5 years. Because all other Idea group events works like that.
Some AI takes this idea group in mid-game. Some AI countries have higher change due to their history. (like timurids, mongolia)
