The first pack I would
get is
your local pack if there is one. The familiar animals can be a great starting point for building habitats and recreating zoos in your area.
Beyond that, check out the animal roster and see what you're interested in. Everyone has wildly different tastes. The base game is kind of lacking South American, Australian, Temperate/Cold Climate animals, Southeast Asian, and aquatic animals. If you are interested in those groups, you might want to get packs that address those gaps. Also, The quality of the animals has increased over time. The newer packs' animals will generally look nicer.
Here is a general ranking of what I would recommend, but I strongly encourage you to start with your favorite animals and possibly building themes if you picture yourself getting into building right away:
- The base game doesn't have much for aquatic animals, so you might want to pick up some of those. The aquatic pack has a seal, a penguin, an otter, and a cute caiman. It also comes with some useful recolorable rocks and a recolorable build set. It is one of the most popular packs though it's not a personal favorite of mine.
- The grasslands animal pack does a good job adding things from regions that were lacking. South America gets the maned wolf and armadillo; Australia gets the sorely needed emu and wallaby, and the Middle East gets a striped hyena and the caracal. This starts to address the gap in the the roster for Australia. You could exchange this with the Australia animal pack.
- The conservation pack has some great animals that were highly wished for by the community: a gibbon, the wild horse, a leopard, and a desert oryx. It also has some great pieces for building and decorating your habitats to make realistic work areas.
- The South America pack is basically essential for building a South American section. The base game only has a tapir and a giant tortoise. The jaguar has a black morph which shows up frequently and looks nice. Capuchins are cute if a bit loud, anteaters are awesome, and the llamas are funny. The building pieces are not typical favorites, but this pack does add bamboo walls and ruins for building jungle habitats.
- The North America Animal pack adds 7 animals (moose, mountain lion, arctic fox, prairie dog, beaver, alligator, and sea lion) instead of the usual four. It doesn't come with scenery, but I and quite a few other players would gladly make the trade. There isn't much for temperate animals in the base game, and this pack has a fun variety that will encourage you to build different habitats. Each habitat for this pack will look vastly different. If you don't care for North American animals, this niche could also be met by the Europe pack instead, which comes with a nice set for building.
- The Tropical pack adds another gibbon, a red river hog, a fossa (which hunts lemurs, of which there are 3 in the base game), and an Asian water monitor. Southeast Asia has a lot of cool animals that I personally was less familiar with. If you like the roster better and aren't interested in the scenery (this pack has a good set, but it is kind of niche), you could swap it with the Southeast Asia animal pack, but there are some quality issues with those animals.
- The Africa pack has a popular roster, but the scenery is mid. An African rhino seems essential to a zoo game. I like the African penguin better than the king from the aquatic pack. The meerkat and fennec fox are iconic and cute as well. It is hard to go wrong with these animals. If you don't care about the penguin as much, I might consider exchanging it with the Arid pack, which also has an African rhino.
- The Wetlands Animal Pack has some very niche animals and some adorable favorites. Capybaras are awesome, and I love the Asian small clawed otter! Australia gets the iconic platypus, and this pack adds a bird. I prefer this otter an caiman to those in the aquatic pack. This pack also has 3 random animals. It's a nice pack, and the animals are of good quality.
- The Australia Pack adds some iconic picks from an underrepresented continent. The cassowary, red kangaroo, and koala seem essential to me. The build pieces are rusty and interesting, but their colors aren't flexible. The building set is thus mid. The animals are of great quality except the koala, which is ok.
- The Europe pack had a great selection of animals. The fallow deer comes in many colors and guests can walk in its habitat. The lynx and badger are cute, and this pack brings one of the two goats in the game. The other is in the arctic pack. You could exchange this pack with North America if you prefer European animals.
- Arid: This is the first pack that I would not recommend to beginners, unless you can't live without the porcupine. Most of the roster is hoofed animals that will live in nearly identical habitats. I actually love these animals, and I'm glad it fills out North Africa. It has a lot of nice filler that I appreciate as I build bigger zoos.
- Twilight: I also would not recommend this pack to beginners. The animals are cute, but not as essential as other additions, and this pack adds a lot of filler. The base game doesn't have much for small animals, so you should consider it eventually and especially if you want Halloween/spooky decorations.
- Southeast Asia: The roster is interesting. There is a wide variety of animals that mostly look nice. The Malayan Tapir is the worst animal of the pack, which I'm sure you'll hear so much about you'll be sick of it if you stay with the community for 2 weeks. You could exchange places with the tropical pack if you like the overall roster better. They've fixed the worst issues in everything but the tapir.
- Arctic: I would not recommend this pack to beginners. These animals are tricky to build for, and the scenery is very niche. This pack is perfect if you like Christmas/snowy buildings. It also adds polar bears and caribou, which are iconic tundra animals even if they don't show up in many zoos.
- Deluxe DLC: Get this on sale. It usually comes on sale for $3. The pygmy hippo is awesome, and the komodo dragon is a staple of Southeast Asia. I love all of these animals, especially the gazelle, but it isn't worth the regular price.
The order of my personal favorites from most to least favorite, if you were wondering: North America, Grasslands, South America, Arid, Conservation, Australia, Africa, Twilight, Wetlands, Tropical, Europe, Deluxe, Arctic, Southeast Asia, and Aquatic.
Personal biases at play: I don't usually make fancy buildings, I prefer animals, I'm from North America, I played zoo tycoon, and I don't like building semi-aquatic habitats.
