Please consider adding a one city challenge (OCC) civilization to Civ 6. Venice in Civ 5 was a very popular and fun civilization to play and it is definitely possible to make a similar fun challenge to Civ 6. As you are adding new leaders right now this is a perfect time to do that.
Add a new leader to lead any city-state. The new leader could be someone historic that has lead different city-states or it could be someone vague but for the purpose of this suggestion, I’ll call it “The Council”. The Council appears on the leader selection screen as usual but upon selecting, you get a popup or a dropdown window to choose which city-state you want to play as.
Selecting a city-state grants you its suzerain bonus ability for the game as the civilization ability.
Note: This mechanic would grant some extra replayability to otherwise similar OCC games. Choosing a powerful suzerain bonus at the start of the game also makes for a fun yet important decision.
Most mechanics of the OCC game would be defined by The Council leader abilities:
No city annexing: Capturing an enemy city grants you an option to “raze city” or to “liberate city”. Liberating a city causes it to become a free city. Can not flip free cities to your empire with loyalty. Loyalty pressure keeps the free city from flipping to any other civilization.
Note: Obviously, an OCC game shouldn’t be able to capture cities.
Unique settler: Replacing the usual settler, the unique settler can settle only the capital city and has one charge for extra action.
- Puppet free city: Use the unique settler charge next to a free city to turn it into a random city-state with 3 envoys. Using the ability on a former original capital turns it into a generic city-state that keeps the capital name and offers no unique suzerain bonus.
-Build unique tile improvement: Use the unique settler charge in your own territory to build the unique tile improvement.
Note: Just removing the settler from the OCC game would be a bad idea. The game has so many ways to get free settlers or to boost settler production. All these could boost the unique settler instead. Also capturing an enemy settler would turn it into the unique settler. Now the purpose of that unique settler could be something interesting like turning free cities into city-states, similar how in the barbarian game mode works or making some cool tile improvement.
Special domination victory condition: Become the suzerain of all capital cities.
Note: Some extra challenge for the expert players. Use your military to turn all enemy capitals into free cities, then use your unique settler to make them into city-states and then make sure you have suzerainty over all of them.
Unique tile improvement: Use the unique settler to build a “Town” in your territory. Towns can not be placed next to a city center or next to other towns. Can not be removed. Provides some or all of the following bonuses: extra yields, adjacency bonus for districts, housing, governor slot, “town wonder” slot.
-Town wonder could be something similar to national wonders from previous games. Only one allowed per empire, they are unlocked from the tech and culture trees. Can be built by unique settler using a charge on the “town” tile improvement. Various significant bonuses depending on the building: National library grants science or writing slots, Heroic epic grants boost to military production or special promotion, grand temple grants religion boost ect.
Note: First unique tile improvements and their wonders come much cheaper than the later ones due to the increasing cost of the settler. This mechanic would create interesting choices especially if you need to use some unique settlers to create city-states from enemy players. Also the town tile improvement makes sense, a lot of the city-states alteady in the game are actually small countries with multible towns.
Great city: The councils leadership allows the city to work additional tiles.
Note: The usual 3 tile radius for the city might be too cramped. Allowing to work, build districts and wonders four or maybe 5 tiles from the city center would make for a much more fun game to the OCC.
Expanding trade network: Completing a trade route to a new civilization or a city state grants a new trade route.
Note: Some mechanic would be needed that grants the civ additional trade routes. This idea scales with the number of civilizations without granting the trade routes too fast. Sometimes the player could face an interesting decision when in need of a new trade route: should I make a far trade route that takes a long time to complete or resort to violence with a closer neighbor and turn one of its cities into a city-state.
Governor system: Allows assigning more than one governor to the city at the same time.
Note: All those extra governor points can’t go to waste. Governor slots in the city could be increased by the unique tile improvement built by the unique settler.
Sorry for the long post. I hope the developers give this suggestion some thought and imploment it in some way.
