Probably but I always play test my changes and that change would go into a. Area I do t know enough about yet.
Seeing all the goodies - great stuff, Frogboy.
Let me elaborate on my idea a bit more. Today, the character (loyalty) game feels rather static. What I have in mind is making it more dynamic as a "resource" of sort. I.e. many thinks (policies, exec. decisions) affecting gov loyalty not only once, but with persistent decrease/increase per turn. That would make you think twice: can I afford to enact this exec. decision, won´t it drop the loyalty too much? Aka in CKIII: can I keep the levies raised for another siege or two, seeing the loyalty of my vassals dropping?
The loyalty itself should have pretty tangible effects on planetary output, apart from producing revolts, donations etc. We should, of course, have tools to increase it - but again, there would be opportunity costs enacting these instead of others.
Perks, ideology, technology etc. can all affect this, you choose.
