I remembered today that CA took something out of E:TW for the most part: Missions. For those who don't know in Rome total war and medieval 2 total war you would have entities, either the nobles or the papacy or the senate who would come up every once in a while and give you missions like, take this territory, or build this building, and for this you would get a reward, or penalty if you didn't do it. The mission structure still exists in the game, and can be seen in the first turn as france, britain or spain when you receive a mission telling you to grab a few territories in order to absorb your colonial empires.
I like changing the minsters around in my governments, but i started thinking of a system where your government provides missions. In a parlimentary system a government, stays in power as long as the people favor it, and often comes into power with a specific plan. If they don't fufill their plan often the government is voted out of office by the people and the opposition comes into power.
So i thought what if every time you had an election you got a mission? This mission would only last as long as the current government, by this i mean set of minsters, is in power, and if not fulfilled the government's popularity would take a massive hit. The reason people would be incentivised to do these missions is because if not your government would lose power, and you would lose all of the experienced ministers who have gotten better at their jobs in the eight years they've been in power.
Furthermore what if you had two different idealogies between the opposition and the majority? For example you could have a more liberal party in the majority focused on social development and freedom, which would grant you missions like 'research emancipation' or 'build a new trade port'. Then when they get voted out of power a more militaristic conservative government comes in with missions like 'build 5 units of line infantry' or 'take flanders'. The nice thing about the two parties is that if for example you like the militaristic missions, you can continue to get them by doing them. Doing the missions keeps the party in power, and with that party in power they will continue to give you the missions.
This type of thing could be implemented in a parlimentary or republican system to expand the governmental gameplay mechanics. As a monarch though noone can give you these missions because your government changes at your whim. Perhaps your allies can give you missions to help them out because a kings word was their bond at the time?
This is just an idea, and i don't know how it could be modded in or if it's even possible. Feedback?
