If a natural wonder is inside my border, but 5 hexes away from city center, will it provide any bonus?
It gives its yield regardless where it is. You can't work it anyway.What about the national parks? Will it give bonus if outside 3-hex radius? What if 2 tiles of the parks are inside and 2 are outsides?
Well... getting a chance to build a NP completely outside the 3-tile radius is almost non-existent. Usually it's well into the 3-tile radius or one tile going further out. A NP is investment, but usually worth it. In the late game you can usually afford to lose some tiles in some cities. Or even found cities just for NPs and then build the NPs close to the city center taking up lots of otherwise workable tiles.So it's best to make national parks outside the 3-tiles radius?
I'd like to add that you should connect all resources (except bonus) inside your borders. You don't have to work luxuries and strategic resources to receive them. And resorts can also be outside the 3 hex ring and you'll get the the tourism.
No. Just build improvements over resources. Not like in older civs in which You connect with roads.So one should build roads to mines, plantations, etc? This is news to me for Civ 6.
The only use for tiles 4 hexes away are Adjacent bonuses. I.E. build a farm on 4th Hex to boost the 2 farms on the 3rd hexes. If that 4th Hex cant be used by another city then maybe a Fort, Air Strip or Missile Silo from Military Engineers.
So it's best to make national parks outside the 3-tiles radius?
Since all 4 NP tiles have to be in the same city, doesn't that limit them to workable tiles? (Or else how would you know what tiles are within a particular city?)
Edit - I guess the tile Tooltip tells you what city has the tile - but you can't change anything beyond the 3rd ring, right?).
I really don't understand the whole "must be owned by the same city" requirement. It just makes national parks annoying to micromanage, especially in the instance you identify where you have available tiles in the 4th/5th ring but they are owned by different cities, and there's nothing you can do about it.
