As for the GUI the propaganda & media control could be just a new area, with some slimple sliders, like % of contend censored, daily budget. The more media are censored, the more people will emigrate out of your country and you could improve your approval by 1-8%(I'm not an expert at sociology, it could need more reference to be realistic). This could cooperate with, already posted somewhere here, migration control like closing borders etc. A country with full censorship, closed borders and full control over a citizen is a dream of every authoritarian ruler
Propaganda actions/campaigns could be something like research projects where you set the target country(may be yourself), its aggressiveness/strenght( 3 or 5 degrees), duration(days) and style (positive, negative or maybe "nuke approval"), and you get a calculated cost of it (again, the specific calculating formula needs someone more experienced). The effects would be for example:
1) positive campaign at your country: cheap, + some approval, none global effects.
2) positive campaign at another country: more expensive, slighly incresead diplomatic relations(ex. +3%), a bit more increased, than diplomatic, civilian relationship( +4%), - 1-2% casus belli on both sides, but only if below 40-50%, none global effects.
3) negative campaign at another country: the most expensive one, badly decresed diplomatic relations with that country and all his allies, slighly decrease civilian, + casus belli for both sides, bu 4-5% more for you, global effects to be revied(not sure, but would +1-2% CB on you be ok?)
4) negative campaign at your country: pointless, but possible, i think it needs no description.
5) nuke campaign at another country: the longer it lasts, the lesser the penalty when you use A-weaponry agaist that country, of course impossible of decreasing the penalty to zero.
It would be best, if the effects of propaganda would be uptaded daily, but i'm aware the easiest to code would be a research-like effect after it ends.
Hiding military causalties, could be just 2 sliders: money you spend fo it, and % how strong it would be hidden. The realistic factor could be, the more you hide, the slower you military aprroval falls (or don't fall at all), but the bigger is the chance that it comes at daylight and your civilian approval falls. On the other hand, the more money you spend on it, the lesser is the chance that it fails. Checking for fail could be daily, weekly or monthly, depends whats easier to implement.The strenght of effects and cosequences of media control, propaganda etc. could ofcours varry with the goverment system, for example for a democracy the emigration rate would be far higher than for a totalitarism/theocracy. As for the list or map, the only list could be one just like in research, only showing ongoing campaigns along with progress bars, there would be no need to show anything on the map.
As for provocations/false flag actions, that could be a feature added to the inteligence menu, as two separate bookmarks. A provocation would work like that: selecting the target town, facility or ship(of an enemy country), assigning the number of spies that participate on it, money and date(not essential, default the next month after giving order). The factor's that affect the succes of such an action could be: the number of spies, their experience,time they had to prepare money and the enemies counter-intelligence. the effect could be depending on grade of the succes - max: high CB for that country on you, no global effects, worsened diplomatic & civ relations; min : low CB, worsened diplomatic & civ relations, slitghly worsened diplomatics with all non-allies, low CB on you for all non-allies.
False flag attacks, would be very similar, but the target would be your town/facility/ship at you would have to select a target country. The succes would depent on your military and civ approval, money,preparing time, number & experience of your spies and media control. Effects max: high CB on target country, very slightly worsened approval, min: very worsened approval, no CB.
Ofcourse, the effects of those all actions need to be confirmed/changed by someone more competent in this area than me, i wrote only suggestions that seem for me quite reasonable.
I think thats enough for now
if something is still not clear or you have any questions i would be glad to answer them, and i'm very happy that you are interested in my idea.
jeez, the last time i wrote something so long was on my matura exam
