I'm pretty new to civilization 6 and its amenities system
One thing that is for sure is, one luxury resource yield 1 amenity point to the first 4 cities that need it the most. The question is about the 2nd copy of this luxury resource, would it extend to the next 4 cities ?
There seems to be this belief going around that having multiple copy of luxury resource will have its benefit provided to the next 4 cities. I had this belief too, implicitly, before even researching online about this matter; it make sense to be so after all.
However, from my very crude testing, it seems that multiple luxury resource does not yield its point to the next 4 cities and thus having multiple copy of luxury resource doesn't seem to have any benefit other than trading them off with another civ. However, my test is very crude and I'm not too sure if there is any other condition affect this amenity thing so I'm not too sure about this test. Does any one have any idea about this matter ?
Edited according to @scottn and @Michael Campbell's answer:
- Before world congress was introduced multiple copy of luxury resources do not provide additional amenities.
- After world congress was introduced multiple copy of a luxury resource can provide additional luxury point if the world congress has voted for that luxury resource to be so.
