City-State mechanics appear to be more of the same but improved to make it feel less gamey. Here are the details we know so far.
From Quil118's preview
-Assign envoys
-No more influence meters
-example given: more envoys = stronger bonuses related to city state bonus
-At a certain level, City-States become your ally
-Envoys can be reassigned
-Quests are still in; Gain envoy with completing quests
-His opinion: City-State relations will feel less grindy and spammy and more stability to relations.
From RPS article
The article seems to suggest the city-state in the preview build was actively involved in the diplomacy of the map, and not merely passively giving quests and picking fights randomly with other ciy-states.
New Info from 2K
- Quests only become visible after envoys are sent to a City-State (Author's speculation: This may reduce the quest spam from non-aligned City-States, but also mean relationships are more targeted and focused)
- Completing a City-State’s quests earn additional Envoys there, which help you enact more influence and earn greater rewards as you continue to strengthen your relationship that particular City-State
- Envoys: earn resources over time, the more envoys sent the greater influence the player has with that city state.
- With enough influence, you can become Suzerain of that city-state
- Currently there are three bonus tiers show plus a Suzerain bonus specific to that city state and a Diplomatic bonus
- Screenshots show bonuses up to bonus 3 for Jerusalem and Hattusa and bonus 6 for Zanzibar
- Speculation: Bonuses likely tied to # of envoys. With up to 6 envoys possible , at 6 envoys, players get bonus 6. Players with most envoys gain Suzerain bonus.
- Unknown mechanic if there is a tie of 6 envoys from different civilizations to a particular City-State
- Each city gets a unique bonus Confirmed by Ed himself
- May Pay gold to temporarily take control of the city-state's military forces
- May Send envoy to a City-State they are at war with, potentially changing the City-State’s allegiance in the middle of the conflict
- There will be a mechanic to remove envoys - To be announced
Government Cards
In the E3 Twitch Preview, two Diplomatic cards are shown to have City-State modifiers. Both are Diplomatic Cards
Diplomatic league- The first envoy you send to a city state counts as 2.
Charismatic leader- +2 influence per turn to earning a city-state envoy.
Noteworthy information: Envoys earned via 'influence' currency.

From RPS article
A City State to the northeast of my capital (Beijing) marked my first contact and there were no problems there, but as soon as I met my American neighbours, rumblings of discontent were heard.
All of that goes back to the reactive nature of the AI. Even the city state had involve itself, choosing to side with the Americans and producing armies of its own.
