Flight & Improvement:
Flight tells us that all improvements that provide Culture generates Tourism. This is true but misleading and incomplete. The game has a list of tile improvements that are allowed to generate Tourism at Flight. In this list they are all tile improvements that generate Culture (except the Nubian pyramids…), but also those that could generate Culture thanks to the tile improvement itself under circonstances, like a Pantheon or playing a peculiar civilization. It means that a tile improvement that gains Culture from an outside source like a natural wonder, a world wonder or leader ability but is not part of the list is not going to yield Tourism at Flight. Something to mention: you don’t need to work the tile for Tourism, but the tile has to be in a workable range (within 3 tiles of the City-Center) to produce Tourism. If you put an improvement further away, it will appear to produce Tourism on the Tourism lens, but the lifetime accumulation will always be 0.
They are also some tile improvements that yield Tourism at Flight but use Faith or Food instead of Culture. Here the list:
- Culture to Tourism
- Base: City Park (Liang, governor), Mine, Pasture, Plantation, and Seastead.
- City-States: Alcázar (Granada), Batey (Caguana), and Moai (Rapa Nui),
- Unique: Château (France), Chemamull (Mapuche), Golf Course (Scotland), Great Wall (China), Ice Hockey Rink (Canada), Open-Air Museum (Sweden), Pairidaeza (Persia), Sphinx (Egypt), and Ziggurat (Sumeria)
- Special: Features with the Marae building (need explanation).
- No Tourism: Nubian Pyramid (Nubia), and Vampire Castle (Secret Societies game mode)
- Faith to Tourism: Colossal Heads (La Venta), and Rock-Hewn Church (Ethiopia)
- Food to Tourism: Kampung (Indonesia) (need explanation).
Pastures, Plantations and Mines are peculiar. They gain additional Culture with God of the Open Sky (Pantheon, +1 Culture to Pastures), Goddess of Festivals (Pantheon, +1 Culture to Plantations), or when playing as Gaul (+1 Culture to Mines). Therefore, those tile improvements generate Tourism at Flight because they can have Culture naturally: the game has set the “Culture to Tourism” on for those tile improvements. If the tile has Culture from the ressource, like Coffee & Silk for Plantations or from Amber & Jade for Mines, then that 1 Culture will not generate Tourism. A Gallic Mine over a Jade, yielding 2 Culture (1 from Jade and 1 from the Mine), will generate 1 Tourism at Flight.
But: the Pastures, Plantations and Mines are not locked to only work with the Pantheons or as Gaul: it can work with everyone. If you manage to have Culture on those tile improvements, then it will also yield Tourism at Flight. For example: the Chichen Itza gives +2 Culture to rainforest. A Banana plantation or a Diamonds mine over a rainforest will generate 2 Tourism each, with or without Pantheon or as or not as the Gallic. But other tile improvements on rainforest like Lumber Mills or Ivory camps will not generate at Flight with the Chichen Itza because the “Culture to Tourism'' for those tile improvements is set to off. It might be unfair to some extent, and I agree: this is just how the game works.
It also means it is exploitable in some extend::
- Have the improvement on natural Wonders that give Culture like the Eyjaflallajökull, Matterhorn, Mount Vesuvius (it gains Culture from eruption), Païtiti, Piopiotahi, Tsingy de Bemaraha or Uluru.
- Have the improvement (including: Pastures, Plantations and Mines) in the tundra when the city has the Saint Basil’s Cathedral wonder.
- Have Plantations and Mines in the rainforest when the city has the Chichen Itza wonder.
- Leading America as Theodore ‘Bull Moose’ Roosevelt, have the improvements with breathtaking Appeal next to Woods or world Wonders.
- Leading France as Catherine ‘Magnificent’ de Medici, have Plantations and Mines on luxury resources next to a Theatre Square or a Château.
- As the Maori, having the improvement (including: Pastures, Plantations or a Mines) on a passable feature in a city with the Marae.
Now, for the special cases:
- The Marae (unique Maori Amphitheatre) has the ability to give 1 Culture to features like Floodplain, Marsh, Oasis, Rainforest, Reef or Woods, including passable wonders like the Cliff of Dover. At Flight, each of those tiles will yield exactly 1 Tourism, even if it has more Culture than that. It is not all: the Culture can also be used with the tile improvement! If you have a Diamonds mine on a feature, you will end up having 2 Tourism for 1 Culture: 1 Tourism due to Marae, and 1 Tourism due to Mine.
- The Nubian Pyramid can have Culture if adjacent to a Theatre Square, but do not have the “Culture to Tourism '' at Flight. It might be an oversight.
- Colossal Heads and Rock-Hewn Church work the same way, instead it converts Faith into Tourism. As for the Culture one, you can enjoy the additional Faith input to increase the Tourism like those in Pantheon (Earth Goddess: +2 Faith from Breathtaking tiles, or Fire Goddess: +2 Faith on Volcanic Soil), improvement (Nazca Line (from Nazca city-state) that adds Faith to adjacent tiles (and Appeal)), or from natural Wonders (like: Delicate Arch, Mato Tipila, Mount Everest, Mount Roraima, or Uluru).
- Kampung is the same but with Food. As a Mine over a Jade, the base Food from Coast doesn’t count. But the Food from Lighthouse do count. The simple math is Food minus 1 is equal to the Tourism output of the Kampung.
