Each copy of a luxury provides amenities to four cities. If you have 5-8 cities, then you'll need two copies to give one amenity to each city.

I keep hearing that this is not true. I'm too lazy to test it myself.. someone has probably done it

I gave away a bunch of excess luxuries and on the next turn my city amenities and happiness was unchanged, I had 16 cities when I tried.

So all your copies of one type is only good for 4 cities and some trading

I think it's simpler than this but may be wrong.

As I understand it, basically your total amenities from luxuries = number of unique luxes you have x4.

So if you have 30 total population (no matter where they are located) and 6 unique luxuries you've got 6 x 4 = 24 total amenities to distribute to 30 population. You'd need 6 additional amenities from other sources (buildings etc) to make up the difference.

That's a simplified version of it. It's much more complex in practice because a single city can't have multiple amenities from the same luxury. Or at least I don't think they can. Possibly I am wrong about this. Where it would really matter would be like a hypothetical Venice one city challenge. A single city probably can't get multiple copies of the same luxury. So if Venice started with diamonds, silk, and spices, I think they would only get +3 amenities for that city, not +12. If they built additional cities and grabbed no new resources, each city up to the first 4 would also have +3 amenities from luxuries. I think.

Pretty sure it's one type of luxury for 4 cities, no matter how many copies you have. But that's typically the type of things that should be clearly mentioned in the civilopedia.

I haven't actually investigated this. I'm just repeated what I've seen on YouTube. Has the implementation changed since pre-release? Does the AI know that?

It is just 4 amenities from a unique luxury. Extra copies of that luxury provide no additional amenities, regardless of how many cities you have.

As for the question posed by the OP (why does the AI seem to want to buy extra luxuries?), that is probably an AI trading glitch, and not any indication that somehow extra luxuries actually have value to the AI.

Another AI trading glitch is that they want so much gold from you if you are trading for lux items at first. However, if you put a lump sum of 100, then ask to make it a better deal, it will drop the gold per turn to a reasonable 3-8 gpt instead of the 22 they insist on at first.

I can confirm it is only 4 cities per unique luxury no matter how many copies you have them. I have a game where I have 15 cities, a ton of copies of each luxury and my cities only get 44 amenities total from 10 types of different luxury. Two of those luxuries are from Zanzibar and those give 6 cities each.

This probably is a smart way to avoid very wide empires.

Back to the OP, if the AI is buying copies it already has, you should report that as a bug. That's a great exploit for the player.

Are you serious?! I thought the entire point of "Each luxury only helps 4 cities" was specifically MADE to alleviate the uselessness of extra luxuries by actually giving them a purpose beyond trading them away for of "literally anything at all". Are you certain that having extra copies does frick all again? If so that is so monumentally stupid and completely backwards.
