@How to know , the most pertinent point you raise is one I have skipped over without realizing it: how do Great Ministers and Great Revolutionaries appear in the game, and how must that mechanic be different from the other Great People?
And, as an aside, is the mechanic so different that the Ministers and Revolutionaries need to be in an entirely new category of named people in the game?
To deal with the second point first, I have used the terms Great Minister and Great Revolutionary so far because, on the one hand, they are so perfectly descriptive of the effects I'm looking for, and, on the other, everyone is already familiar with the Great Person system and so elaborate definitions are less necessary. You are absolutely correct, however, that their effects are designed to be much more far-reaching and 'game changing' than those of the other Great People, and so perhaps they need to fall into an entirely new category.
I just, at the moment, have no idea what to call that category. I'm open to suggestions.
As to where the little digital Minsters and Revolutionaries come from, here are my initial thoughts:
Great Ministers are not received completely by choice - by things the Gamer does specifically to get them. Historically, Great Ministers were appointed by the Leader, and frequently removed when it turned out to be a bad or uncomfortable choice. They could also be removed by force, either from the Leader or other elements of the Civilization. Importantly, their appearance is at least partially Random, because the Leader’s judgement as to what/who he/she was appointing did not always result in a Great, or even Mediocre Minister.
So, since the Consequences of a Great Minister are more important Civ-wide than that of any other Great Person or Governor, the mechanic for receiving one has to be something different as well. I suggest the following:
Great Ministers are appointed by the Civ Leader. However, since the Leader’s ‘choice’ does not always result in a Great Minister, each appointment has a percentage chance of resulting in just another Ordinary Minister, and no change in the Civ. Every failed appointment increases the chance that the next attempt will succeed. The occasions when an attempt can be made to appoint a Great Minister are:
1. When the Civ changes Eras or Ages (I do not think Golden, Normal or Dark Ages should be directly connected to the Eras, which I also think should be much more variable than the artificial and rigid Eras in the game now, hence this distinction)
2. When the Civ gets a Great General or Great Prophet or Theologian, that Great Person can be exchanged for a new Great Minister (This
always results in a new Great Minister, but note that exchanging Generals or Theologians/Prophets for a Great Minister does not mean that you will get one with either military or religious effects)
3. Whenever the current Great Minister is lost for any reason.
4. Whenever the Civ concludes a Civil War or Revolutionary Event.
5. Whenever the Civ changes governments.
You can only have one Great Minister at a time, so when/if you successfully appoint a new Great Minister, the old one is instantly replaced. You may also, at any time, remove a Great Minister without appointing a new one. Note also that having or not having a Great Minister does not in any way change the chances of getting a new Great Minister from Events: if we wanted to complicate the game enormously, there are plenty of historical examples of Civs that had more than one Great Minister of some kind at the same time, but introducing that into the game would complicate the interactions between the Uniques and attributes of Leaders, Civs and Ministers beyond what I think is either necessary or desirable.
Great Revolutionaries are normally Unwanted, so you do not directly ‘choose’ to get one or (normally) make any effort to increase your chances of getting one - unlike all other Great People or Great Ministers.
Instead, Great Revolutionaries happen to your Civ, like Hurricanes, Volcanoes, Droughts, etc - they can be regarded as Natural Disasters on two legs that tend to affect the entire Civilization instead of just one unlucky City.
Some of the occasions that may result in a Great Revolutionary are similar to those that result in a Great Minister - both personages could be regarded as the Civ’s general response to an event as opposed to the Leader’s chosen response to the Event:
1. When the Civ goes into a Dark Age or ends a Golden Age: both of these are Events leading to dissatisfaction (to say the least!) among the Civ’s population, raising the chance that someone is going to be upset enough to try to do something Revolutionary about it.
2. Whenever the Civ changes governments. Someone always preferred the old government to the new, and may express their opinion in a Revolutionary Way.
3. Whenever the Civ has negative Military Events. Examples:
- Losing a city to an enemy force
- Losing two battles in a row
- Losing its Capital
4. Whenever the Civ has negative Civil Events. Examples:
- Losing Population to a Natural Disaster
- Having more than 10% of its Districts Pillaged/damaged by Natural Disasters
- Having a City change to a foreign Religion
Great People may become Great Revolutionaries. Basically, what you thought was a Great Writer becomes radicalized by any of the above Events, or a Great Merchant loses too much Gold to a Natural Disaster and decides the Leader/Government need to change to protect his interests, or a Great General decides he would make a better Leader than the current Leader and a percentage of the army agrees with him.
You can only have one Great Revolutionary active in a Civ at the same time, but you may get sequential Great Revolutionaries if Bad Things keep happening to or in your Civ: as soon as one Great Revolutionary does his thing and is used up, another appears the following turn and you start imitating the famous clown act with the plates on the sticks, racing from one to the other and trying to keep everything spinning . . .
I would appreciate any additions or comments: this is a very rough first draft of thoughts on the subject and probably needs a great deal of work.
