1) Przewalski Wild Horse. Should be a must. I mean, in a geographic based pack I don't think they would be included, after the SE Asia pack we could rule out the "whole Asia pack", so there are two options: cold Asia of Eurasia. But I think the most probable scenario is that we get them in a pack like this.
2) Wisent or European Bison. I know we have the American bison in game, but I've always loved the European one, and I think that their recovery story is really inspiring: not so many years ago thy were hunted to extinction in the wild and now they are ranked as near threatened. And, although tecnically they are no longer a threatened species, due to their reduced current wild range and their history they should be here. Another option would be the black rhino, as I'm suppossing we would have finally got the white rhino in an African pack, so adding the black rhino here would be awesome as well.
3) Scimitar Horned Oryx. An extint in the wild antelope, should be in this pack. And even we already have an oryx species, I think that this one is really distinctive. Also, it has been reintroduced into the wild, I think a couple of herds so far, so slightly recovering. As an alternative, another extint in the wild hoofed animal, the Pere David's Deer, which has also been reintroduced in the wild.
4) Amur Leopard. I've always been fascinated with this subspecies of leopard, with leopards in general as well, but the rarity of the Amur leopard is fascinating for me. In 2007, just 14 years ago, they were estimated less than 30 wild individues, and in 2019 they were already aroung 90, but even with that increase they are one of the most, if not the most, rare cat in the world, and they should be included here.
5) Iberian Lynx. From one of the rarest cat in the world in the Amur leopard to another of the rarest cat here. They are a symbol for conservation. Growing up I'v always heard stories about this lynx, about the efforts and it seems that were are seeing some success finally, as their numbers are getting close to a thousand individuals.
6) Coquerel's Sifaka. Lemurs are one the most endangered primates in the world, and not only some species, every lemur is threatened by deforestation and poaching. Also, the lemurs we have in game are way different from the sifaka, which would requiry some unique animations, such as the kind of jumping they do in the ground, so I think they would be really cool in game. They could also go with the Verreaux's sifaka.
7) Grey Crowned Crane. And finally some bird representation. There are many species of bird that could be in this spot: the Spix macaw, the Bali myna, etc., but they would be aviary bird, so going with ground-dwelling bird, I go with the African grey crowned crane, which is endangered and a really beautiful looking bird, as well as really common in zoos.
8) Fiji Crested Iguana. For the exhibit animal I choose one of the most beautiful reptiles I've ever seen. I just don't know why but the colors of this iguana are awesome and I really love them. They are critically endangered as well. Another opction would be the axolotl, to give some representation to the Americas, because I've just realised I haven't include any animal from South or North America.
