Overview of Mechanics

From the most recent video:

Settlements can work tiles up to 3 hexes out from the capital but can claim territory beyond that (just like civ 6)
Settlements must have a minimum of 3 hexes between them (just like civ 6)
Rural and urban districts culture bomb adjacent tiles
Settlements settled on non-navigable rivers or adjacent a navigable river get a fresh water happiness bonus (you cannot settle on a navigable river as it is a water tile)
Specialists provide a base 2 science and 2 culture (can be more based on district), while consuming 2 food and 2 happiness
Penalty for going over the settlement cap is -5 happiness in each settlement (cities AND towns), capping at -35.
Roads to the capital are automatic unless the settlement is very far away (basically all civs get civ 6 Rome's "All roads lead to Rome" ability)
Merchants can create roads
You automatically have access to the appropriate rural districts (essentially tile improvements), but you may need to research technology to unlock their yields.
Your initial build (your choice between warrior and scout) automatically finishes in 1 turn.
Settlers can defend themselves
Settlers can not be captured, instead they are destroyed
Rivers, rough, wet, and vegetated terrain outright end movement
Scouts have the same movement as warriors (2), but are not effected by rough, wet, or vegetated terrain. Their movement still ends on rivers though.
Scouts have the ability to "Search" which expands their visibility one hex further at the cost of ending their movement.
Commanders can be destroyed but they respawn after a fixed number of turns.

There's probably a bunch more that I'm forgetting about that I'll add if I remember them.

Nice Sumnmary!

I'd add one thing I noticed: at least in the capital, building units seemed to me to be about 25 - 50% faster than normal in early-game Civ VI: it seemed to range from 4 - 6 turns instead of 6 - 10 turns that I remember as being normal without 'extra' effects like Chopping.

That's probably related to the fact that the Army-Army Commander mechanic is going to require more units in general very early - they showed battles between 'armies' of 5 - 6 units per Commander, and several armies under trhe Roman banner, which I suspect is generally more than most gamers built in Ancient Civ VI.

I gotta say I love all of these mechanics

Oh right civ switching

It is necessary to apply political and economic models to be able to understand the historical passages, the political and economic reasons from the ancient age to the Middle Ages, from the Middle Ages to the Renaissance, and the ideologies of the twentieth century. It is inevitable to put the ideologies and the economy and the economic theories together for a correct and immersive simulation.

It is very important to introduce political and economic dynamics for the collapse and birth of nations the birth of England as an economic power from 1700 until 1900, the birth and collapse of communism in Russia, cannot be as automatic as the change of era would claim
