Dev Diary: Wildlife Exhibits
Animals and Plants are a new type of exhibit introduced in Timeline, allowing players to collect exotic organisms for their Zoos and Gardens. They provide a small amount of Tourism (Backpacker or City Tripper) to their Buildings, or to National Parks. Their main purpose however, is to provide additional
amenities in the endgame. The larger your collection, the more amenities they will generate for you. This is important for Civs that care about Amenities such as the
Americans, and less important for the
Chinese, who can instead focus fully on their Five Elements Harmonies.
Mechanically, the principle is similar to that of a card drafting game - every Animal or Plant Exhibit you can obtain exists as a Card, which you can then Display into the corresponding building.
In the game, Animal and Plant Exhibits will be referred to '
Wildlife'
Exhibits, as opposed to Great Works which are
Man-Made Exhibits.
The idea is to later also add
Fossils to the base game (see also the
Paleontology promotion Researchers currently have) which are Wildlife Exhibits that function like
Artefacts, and can be put on Display in Musea (yielding
Knowledge and Tourism). This doesn't include 'living fossils' such as the Coelacanth (which can just be Displayed alive inside of a Zoo). Finds such as a mummified thylacine or a frozen wooly mammoth however
would count as Fossils.
Wildlife Capture Mechanics:
For the Wildlife Exhibit to be discovered, the Researcher must click the '
Capture Wildlife Specimen' button. This action will take 1-3 turns by default. Researchers can choose between targeting Animals, Plants and both. All Wildlife is specifically tied to one specific biome - Grasslands, Plains, Tundra, Tropical or Desert, and most have additional feature requirements.
If the Wildlife Exhibit has one of these additional feature requirements, then those features must be present on or adjacent to the tile the Researcher is standing on when attempting to Capture a Wildlife Specimen.
Terrestial Plants have an additional requirement in that they can
only be found in Vegetated or Wet biomes, or in proximity to specific
resources. (they will as such
never appear on tiles that aren't adjacent to Vegetation or Wetlands, unless the correct resource is also present). Animals may feature similar restrictions but can appear on Open terrain.
Resource requirements can be representative (any Plant that needs to be discovered near a Dyes resource is a source of (natural) dye in real life), lateral ('Olives' represents Olive Oil, so any other plant that also provides a
fragrant oil irl may also require Olives to be present) or Dietary (an Animal that is known for its Fish consumption may require the proximity of a Fish resource)
The Card Pool the researcher can pick from will be visible in the tooltip when hovering over the button, listed as follows:
- The biome of the tile it is standing on
- Any features on surrounding tiles
- Any resources on surrounding tiles.
- Any marine tiles adjacent to its tile. (requirement for Navigable River, River, Lake or Coastal)
Card Rarity & Availability:
When a Capture is made, the player sees up to five potential Exhibits and picks one to get. All Cards shown will be picked at random from the available pool. There won't be duplicates. If there are fewer than five legitimate choices, the player will see that number of Exhibits.
The Exhibit pool is shared between all players, so if a Card is picked by one player, it is removed from the pool for everyone else. Rarity is the value that determines how many copies of a Card are in the pool, which also determines how likely it is to show up.
- For Common Cards, this is five times per game.
- For Uncommon Cards, this is four times per game
- For Rare Cards, this is three times per game
- For Iconic Cards, this is two times per game
- for Unique Cards, this is one time per game.
Every Card can only be picked once per player however. If a pool contains five Rats, and you take one, you won't see any more Rats, and four of the other players can still pick the Rat if they want to.
Wildlife t Exhibits do
not receive theming bonuses when displayed in their corresponding buildings. The reason for this is that determining synergies based on food chains and/or taxonomy gives me a headache

. (Mammals and invertebrates are fairly easy, but do NOT look up birds or fish)
Instead, every Wildlife Exhibit will provide a fixed amount of Tourism depending on the Rarity of the card. Any Cards that you own, but don't display will passively generate Knowledge according to the Card's Rarity.
Displayed Animal and Plant exhibits can also provide Amenities.
The Cards will contain more information than what I'm about to list:
Diet,
Size Category and
Enclosure all determine which Animals can be grouped together with other Wildlife in the same building.
Size Category
Every Wildlife Exhibit is given a Size Category. 1 - 5. This is equivalent to a card's '
mana cost' in games such as Hearthstone or Slay the Spire, and represent the amount of space the Wildlife occupies. For Plants Size 1 is a small flowering plant, Size 2 is a bush, Size 3-4-5 are trees. For Animals, 'Size' represents the animal's place in the food chain, which small prey animals being Size 1, and apex Predators being slotted in categories 3-4-5.
All buildings that can accomodate Wildlife, such as Gardens, and Zoos, can hold a maximum 'size' amount of Animals and Plants. National Parks can do the same.
Size Category also determines which animals can be grouped together based on their diet. An Animal will always consume other organisms
smaller than their Size category. Animals of Size 1 will only consume other Wildife of Size 1.
Diet Category
Diet determines which tags are irreconcilable within the same building:
- Carnivores will consume other animals except for invertibates of a smaller size.
- Herbivores will consume plants up to one category larger than they are.
- Insectovores will consume invertibrates of their size or smaller.
- Pescatarians will consume fish of a smaller size.
- Omnivores will consume any Wildlife of Size 1, and ONLY size 1.
- Scavengers won't consume other animals unless their collective Size outnumbers that of the smaller Wildlife.
Plants do NOT have a Diet Category, as they don't consume other Organisms (this also applies to insectivorous plants, just for the sake of not overcomplicating matters).
Enclosure Categories:
Enclosures group animals together based on whether they are live in water (
Aquatic), on dry land (
Terrestial) or in trees (
Arboreal). Animals only consume other organisms from the same Enclosure category. This makes sense. Put a pride of lions and a family of meerkats in the same enclosure and see what happens. Some animals will have two Enclosure types due to their mixed biomes (an example is the Hippopotumus which is bohth Terrestial and Aquatic)
Arboreal animals will require the presence of at least one
Size 3 Plant (a tree) inside their Enclosure.
Amenity Yields:
Animal and Plant Exhibits can generate Amenities when put on Display inside their corresponding buildings. Plants will provide
Greenery Amenities which increase City Health. Animals provide
Security Amenities that improve City Happiness. I haven't figured out the exact formula yet, but it should scale with Rarity and Size category.
For the players that don't like these sort of mini-games, worry not. I would not introduce such a system without also ensuring there would be a button that allows for
automatic optimization.

And you can still do Tourism the old-fashioned way.
List of Wildlife
This list is tentative (and quite expansive - perks of being a former bio teacher specialized in taxonomy :3) and not quite balanced, but I don't think it needs to be. Most of the Wildlife listed below is either recognisable or interesting, which are the criteria I value most. Balance can be worried about later...x
