How do luxury resources and marketplaces affect my city?
There are 8 luxury resources in the game (Spices, Dyes, Silks, Ivory, Gems, Furs, Wines, Incense). For each luxury resource connected to your cities, you’ll make one citizen happy. So if you have 5 of the 8 luxuries (either domestically or imported from other countries), your cities will get 5 happy citizens. If you have a city with 5 citizens, all will be happy. Marketplaces act as a modifier to this luxury happy citizen bonus. For the first two luxuries you have, you’ll just get the standard 1 happy citizen per each. For the 3rd and 4th you have, you get 2 happy faces each. For the 5th and 6th, you get 3 each. For the 7th and 8th, you get 4 each. This way, if you have all 8 luxuries and a marketplace in your city, you’ll get an amazing 20 happy faces!
