Hey Mjmannella, I totally respect your opinions on the species however I disagree on your thought about Frontier being tone-deaf. If you check the list of the most wanted species here on the forum, you will see that these species are among the ones being the most requested, meerkat and white rhino were on the top actually. I get it its just a small sample of players, but I think its pretty accurate sample. Ask any casual person and I am sure most of them would say that they want a meerkat in game.
As for your though on the small animals, many, many people also wished for smaller species, as you cannot build a realistic zoos without them. A Fennec fox is something completely new as opposed to for example your suggested leopard, which would frankly behave the same way as the jaguar we already have. Overall, I think Frontier finally listened to the most wanted species with these picks. We dont have a fox in game yet, but we have alot of cats. As for the penguin, most zoos would actually have these smaller, more tropical penguins not the big king penguins.
