So, in my play style, I find myself constantly choosing Humanist ideas, since I generally am fairly expansionist and end up ruling over many different cultures. All well and good, I like the idea group as a whole (that and Plutocratic are my favorites). However, I'm curious at what point it makes sense to choose Religious instead (of course, I could choose both) and culture convert provinces of the wrong culture. Has anyone broken down the math on this?
