I dont think anyone here ever really disliked ungulates itself. The negative feeling about them imo came mainly from us getting an excessive amount of them for a long time, with very little in terms of other animals, some of which where very underrepresented at the time.
Like if we got 3 animal packs in a row which all have 60-80% primates then people would be equally fed up with them.
And this is just a personal thing, but in my opinion hoofstock are kind of boring to build for, so for me they are never really the most exciting additions to the game. Still nothing against them in real life tho
For me it has also been a quantity thing. I love the North Carolina Zoo’s hoofstock habitats, they are beautiful. As
@AndyZoos said the Bronx zoo monorail is fantastic. Even other zoos, like the Franklin Park Zoo in Boston has a beautiful habitat for the Giraffe, Zebra, and Somali Wild Ass.
But here’s the problem, outside of a handful of picks, we have so many ungulates in game I can easily make or remake most zoos. Sure I might be missing the Nilgai, Black Buck, and Peere David’s Deer, and those would all be great animals to have (I especially want that deer, my fave

). However, even without their addition we have enough options we can either have reasonable substitutes, or even go without these animals and not have it effect the overall theme. Are there still additions we can use? Absolutely. Is it as pressing as some of the other roster members? Not in the slightest.
Try to make a bird area. You really can’t do it. We have “””””enough””””” birds for
some areas. We have an ostrich for the African Savannah, we got an emu, for European ponds we got the swan. Making an Asian area? You can use the peacock and the red crowned crane. If you are really feeling exciting, you can even make a Caribbean section with flamingos. You can even make a penguin dome! Anything past those specific examples (and a handful of other birds like the chicken) we have nothing. Every continent may now have a bird, but it isn’t the same as every continent having a different ungulate or two for each biome. We are still missing ducks, other cranes, other land fowl. And while it’s never gonna happen for PZ1, a zoo game not having eagles or parrots is like not having a lion or elephant. We are missing some heavy hitters, and the WTE won’t be used.
And the same can be said for monkeys, rodents, reptiles, and don’t even get me started on the exhibit box for amphibians, reptiles, invertebrates, and oh my god
fish.
So no, ungulates themselves are not the issue, it’s Frontier favoring them for so long other sections of the roster have fallen behind. It took over 4 years for South America to get its second monkey, and finally get some birds. In that same time we got so many pigs, goats, antelope, and everything else.
