World's Fair

The World's Fair is the end-game monument building in Anno 1800, available for construction upon reaching the Investors tier of Population. Unlike other buildings, the World's Fair is built over several stages, with each stage taking time to complete and requiring a significant investment in resources and labor from your workforce for the periods of construction.

Upon completion, the building itself grants 150 attractiveness for as long as it maintains access to electricity. While you are limited to one World's Fair per island, you can build as many as you want across multiple islands.

Afterwards, the player can use the building to host exhibitions that showcase the latest advances in 19th century technology, discovery and design to an Investor audience looking to spend money.

Exhibitions grant an additional, temporary attractiveness bonus for as long as they last. The successful conclusion of an exhibition gives the player access to a long list of possible rewards, depending on investments and choices made.

Construction

The construction of a World's Fair is divided into five stages. The first stage requires placing the foundation, which is unlocked after advancing to the Investors population tier. The next four stages, unlike regular buildings, are built over time and require huge amounts of building materials and workforce. Each phase also requires a certain number of investors to be available.

The building will need to receive a steady stream of supplies and electricity, in periods both during and after its construction. This means an in-range warehouse and power plant are permanent features within its placement design.

If a player lacks sufficient free workforce, they can still continue construction on the monument, but progress is delayed. Workforce priorities could always be shifted towards the monument on a temporary basis.

Exhibitions

A player can host exhibitions at a fully built World's Fair. This will allow an eclectic gathering of the world's innovators to descend upon the monument and showcase their latest findings to the player's Investor audience - to charm them into funding their future work. Depending on the type, size and amount of supplies granted to the exhibition to ensure its successful conclusion, the grateful innovators will leave behind donations, which serve as the player's Rewards for hosting the World's Fair.

The donations received, depend on all the steps taken towards a successful exhibition.

The information below will describe all the steps necessary for running an exhibition and how to steer towards a certain reward, along with a running example of one theoretical player trying to obtain dinosaur bones.

Exhibition types; Fields of Discovery and Subjects

The first step the player must decide on is the type of exhibition: The specific field of 19th century discovery that the exhibition focuses on. Each of these fields rewards its own set of possible rewards.

Architectural Marvels - unique ornaments
Science and Innovation - machines and inventions
Archaeology and Ethnography - relics and antiquities
Botany - flora, garden design and musical composition

Each of these fields of discovery is then further subdivided into 9 different subjects. These subjects act like tiers. Higher tiered subjects are more prestigious and difficult to organize for. They also award more temporary attractiveness, which lasts only for the duration of the exhibition.

**List of Subjects that can be showcased during an Exhibition**
		Type of Exhibition
Tier	Attractiveness (Temporary)	Architectural Marvels	Science and Innovation	Archeology and Ethnography	Botany
1	0	City Signage	Basic Tools	Curiosities	Invasive and Wild Plants
2	+100	City Furniture	Basic Equipment	Everyday Materials	Various Trees
3	+200	Plaza Design	Common Seeds	Buried Handicrafts	Aquaculture
4	+300	Esplanade Design	Advanced Tools	Ancient Writings	Flowering Brushes
5	+400	Fountain Architecture	Chemical Research	Rich Furnitures	Colorful Flowers
6	+500	Antique Landscaping	High-End Equipment	Noble Funerary Materials	Lotuses
7	+600	Refined Architecture	Powered Machines	Natural History	Exotic Plants
8	+700	Marine Promenade	Agricultural Revolution	Mythical Artifacts	Huge and Strange-Shaped Plants
9	+800	World's Fair Annexe	Unique Inventions	Ancient Architecture	Mythical Plants

Each of the subjects listed above, has its own unique and/or specific set of rewards.

To begin the running example: Let's say a player wishes to collect Dinosaur Bones to complete their Jurassic Museum Set. The only subject that has a chance of awarding these items, is Natural History. This is a Tier 7 subject in the field of Archeology and Ethnography. In this example, the player should select "Archeology and Ethnography" as the type of their Exhibition.

The player can control which tier of subject is exhibited within their chosen field of discovery, by next deciding on the exhibition's size and supply.

Exhibition sizes

The player can decide to organize their exhibition in different sizes. Bigger exhibitions are more costly, require a larger investor audience to be worth putting on, and more luxurious catering and a longer preparation time during the next step. Bigger exhibitions also make a higher range of subject tiers within a chosen field of discovery, possible for being put on exhibit.

	Modest	Large	Sumptuous
Unlock precondition	5000	7500	10000
Running cost	25000	50000	100000
Preparation time	20 minutes	30 minutes	40 minutes

Depending on the size of the exhibition chosen, the following subject tiers are made possible:

Modest exhibitions: subject tiers 1-5
Large exhibitions: subject tiers 3-7
Sumptuous exhibitions: subject tiers 5-9

To continue the running example: The player who wanted the Dinosaur Bones and therefore needed their Archeology and Ethnography exhibition to be about Natural History (a tier 7 subject), needs the Exhibition to be capable of hosting a tier 7 exhibition. This Player can therefore choose their Archeology and Ethnography exhibition to be either Large (tiers range 3-7), or Sumptuous (tiers range 5-9), as both have Tier 7 within their range.

To narrow the exhibition down to a specific tier and subject within this range, the exhibition will need to be carefully supplied in the Preparation Phase.

Preparation Phase and Catering

After choosing the type and size of an exhibition, the preparation phase starts and the event will need to be catered to with luxury goods in order to make the investor audience comfortable enough to spend money. Should more Investors be available than the minimum requirements prescribe, fewer supplies are necessary. (With more money walking around, less of it needs to be charmed out of each individual for the exhibition to be a success.) The amount of goods can be reduced by up to 50%, when more than twice the minimum required amount of investors participate.

Depending on the size of the event, several goods are randomly required to cater the exhibition. The successful delivery of these goods to the World's Fair will increase the Exhibit's temporary attractiveness bonus to match that of the associated tier.

Most important of all: supplying the World's Fair with goods - or not - can raise or lower the tier of subject chosen to be exhibited, from within the range of tiers previously granted by picking the size of the exhibition. The World's Fair interface will allow a player block the Exhibition's access to one or more types of goods, so that the player can nudge the result towards a desired subject that may be lower within this range.

To finish the running example: The player who wanted Dinosaur Bones and needed their Archeology and Ethnography Exhibition to be about Natural History - which is a Tier 7 subject that can be hosted by both a Large size (subject tiers range 3-7) and a Sumptuous size (subject tiers range 5-9) exhibition - needs to take care to either;

Fully supply their Large size Archeology and Ethnography exhibition with all the requested goods, so that the highest outcome of the 3-7 range is reached, resulting in a tier 7 exhibit, which adds +600 temporary attractiveness and has Natural History as its subject.
Supply their Sumptuous size Archeology and Ethnography exhibition with only half the required goods, so that the middle outcome of the 5-9 range is reached, resulting in a tier 7 exhibit, which adds +600 temporary attractiveness and has Natural History as its subject.

Below is a table of all the possible goods that can be requested to cater an exhibition. For the lavish evening that will be planned during the exhibition, one type of good will be picked out for each of its aspects (Food, Alcohol, Desserts, Decorations and Leisure), depending on the exhibition's size. Electricity is always required.

Goods requirements
Exhibition Size	Modest	Large	Sumptuous
Food	25-50 tons of: Potatoes or Fish or Bread or Sausages	50-100 tons of: Goulash or Canned Food	100-200 tons of: Tortillas or Goulash
Alcohol	50-100 tons of: Beer or Schnapps	100-200 tons of: Rum or Beer	100-200 tons of: Champagne or Rum
Desserts	25-50 tons of: Grapes or Plantains	50-100 tons of: Chocolate or Plantains	50-100 tons of: Fried Plantains or Chocolate or Coffee
Decorations	none	25-50 tons of: Felt or Cotton Fabric	50-100 tons of: Furs or Felt
Leisure	none	none	25-50 tons of: Cigars or Gramophones or Penny Farthings
Access to electricity	required	required	required

Without delivering all the goods requested, players will need to wait until preparation time runs out before the exhibition starts. If all are delivered, the exhibition starts immediately.

The goods demanded will be delivered to the World's Fair from the closest warehouses. Because of this, the World's Fair will require a nearby warehouse, even after its construction is concluded.

Rewards

Every World's Fair Exhibition grants the player three donated items as their reward. Depending on the player's careful selection of the exhibition's type, size and supplies - the exhibition will deal in a specific subject, which has a much more confined pool of possible rewards as its outcome.

However, the rewards earned within that pool of donated items, are still somewhat random.

To learn more about how this randomization works, or to see a complete list of all the possible rewards from a subject's successful exhibition at a World's Fair, see the page on the World's Fair Rewards.

Trivia

The World's Fair was teased a long time before the release of the game, the first post on Anno Union appeared on the 28th of September, 2017. In total, three blogposts and one voting were tied to the World's Fair:
- DevBlog: Welcome to the world fair! (28. September 2017)
- DevBlog: Union Exhibition Vote! (19. October 2017)
- Union Update: A postcard from the world fair (12. March 2018)

The monument is based on The Crystal Palace in London, where in 1851 The Great Exhibition was held.
