Ok so a few things could narrow that list down. If the zoo is making an African complex in Europe, that would mean no bears, lions, tigers, or deer. Maybe eliminate elephants since Asian ones are more common. These animals are eliminated because they aren't from Africa. No lions because of only Asian lions in Europe. If you were building an African complex in Europe and your zoo had financial issues and is bad at raising money, it would eliminate elephants, hippos, and all the "houses" as well as all the animals labeled in the first list since elephants, hippos, and houses are expensive. So the only really interesting animals in a African exhibit in Europe at a zoo with a limited budget would probably be apes, leopards (idk what leopard species are in Europe) giraffes and hoofstock, and maybe rhinos. You would need to have lots of less flagship animals or smaller ones as supporting cast members.
On the other hand, if you were making an African complex in the U.S., and you had to narrow down from premierfong's list, you would eliminate tigers, bears, and deer since they aren't from Africa. You wouldn't eliminate lions since there are African lions in the U.S. If the budget was restricted, you would eliminate elephant and hippos. So there would be a much larger list of animals to have in a U.S. Low budget zoo African complex than in a European zoo low budget African complex.
