So I was just thinking of trade income and I think I thought of a system that works. Countries gain trade income by signing deals with others. The trading countries' incomes are raised by 1 per 10 income their partner has, all sources of income considered except trade itself and gifted income.
So, if country x makes 16 and their partner country y makes 24, country x's income will increase by 2, country y's by 1. I'll think of adding in decimals for numbers in the single digits, but it's unlikely.
Resource rule changes: you can RP for it, getting it for free, or you can start operations to find them. Operations cost 5x, x being the value of the resource which has a max of 5. It is possible to jump straight to a level 5 resource by paying 25 straight, or build it up level by level. It is most profitable to make rp on it, however. You may have only 1 resource per province
Discovering resources also increases your trade value. This does NOT mean you gain more income. Basically, every level 1 resource increases how much your trade partners get by .2. That is to say, 5 level 1 resources raises your trade value by 1; a level 5 resource will do the same. Income will ALWAYS come in whole numbers, so decimals cannot be spent.
So to limit power of trade and general hyper-alliances, how do you guys feel about a 5-diplo actions per turn? This would mean you can only do 5 OFFICIAL diplomatic actions, as in the actions I will post in the thread and that you can still see in the original EUIOT thread.
