I would like to present to you my proposal for the Revolution. Well, I thought that you could divide the revolutions into continents - in this way, each continent would have its own revolutions. In this way, it would no longer be as it is now, for example, the French are doing the Haiti revolution in Asia.
Below is a list that assigns revolutions to regions of the world (revolutions such as the French Revolution will remain unique for a given civ):
On the face of it, it’s a really neat idea and that’s a great list of revolutions, however as much as I’m a stickler for historical accuracy and how I appreciate context-based (map-based in this case) additions, it would always clash with civs playing civs in the ‘incorrect’ map anyway. As a previous poster mentioned Mexico outside of Mexican-relevant maps.
My counter-proposal would be:
Essentially these would function identically to minor civ trade post areas, however would be populated entirely by tents, wagons and campfires, along with a flag denoting what revolutionary/rebel group is camped there.
The difference to a typical native trade post would be that these militaristic camps require investment - offering aside from maybe the odd tech, no units until you spend significant funds.
Every Age would offer a button ‘Support Revolution’ which starts of as a incredibly expensive (almost 'Age-up" level) upgrade, however by the Industrial Age its affordable enough for most civs to spend the resources on. Techincally this means if you are flush with resources in the Commerce Age you could a Revolutionary Camp’s upgrade early (a big gamble). Once ugraded the camp will offer up a roster of units linked to that cause, in a far bigger number and variety than the standard minor civs!
For example on a British map you might find a Jacobite or even Covenanter Camp. When you build your trade post (possibly with a name change to support the context - ‘Revolutionary Headquarters’) and spend a rather large amount of resources on the Support Revolution upgrade (again, most likely in Industrial when somewhat discounted), you will get a selection of units:
Targeteer - Claymore & Targe shield swordsmen
Border Horse - Light pony cavalry
Frame Guns - Super light and cheap cannon
Basically, with large investment comes a payoff of a ‘mini’ army available to train with its own population and in far more variety than the usual Native civs on a map.
I don’t think geography is the best metric to divide revolutions. For one, there aren’t revolutionary nations in most of these places. Revolutionary countries are also far more linked to their mother countries. Location in the game requires a good amount of suspension of disbelief anyways.
If you wanted to restrict or mix up what revolutions are available, I’d make it contingent on choosing certain cards or politicians (kind of like how you get the tank as Italy). I think it could be fun to actually have a secret revolution.
