Australia is in the southern hemisphere, is it not?
Yes. That isn't what I meant.
I only mentioned the northern hemisphere because that is where Frontier is based; Australia fits the 'summer' theme, ergo, when it's Frontier's summer time, an Australia Pack would be a good fit. I suppose they could save it for the Christmas release and do it in the southern hemisphere summer, though, but northern hemisphere players (which doubtless greatly outnumber us southern hemisphere players) would probably think it's an odd fit for Christmas.
I would like to see devils as well however to model them accurately, they would be fighting and injuring each other constantly. At my local safari zoo here in Australia, they have large signs posted around the devils explaining that the patchy baldness, wounds and scars are signs of natural behaviour. While I was reading the sign, two devils who were a mated pair started screaming (the name devil is well earned) and attacking each other. The issue? One wanted to walk straight through the other one, neither wanted to yield so they had a scrap. Then one took two steps to the left and they were each on their way.
Typically after any kind of open wound is received in a zoo the animal gets a quick check-up, but this doesn't always require complete vet intervention. It would need to be simplified in-game for it to be a worthwhile feature, so I guess one thing they could do would be to create two separate 'fight' animations for the devils, one which is a 'regular fight' (i.e. a fight for dominance/space/resources, which always results in injury like with other animals) and a 'devil fight' (which would occur like a regular interaction between the animals, be loud and frightening, but not result in injury). The distinction would be in the animation, but also in the fact that only the 'regular fights' give you an alert.
I don't know much about the Tasmanian Devil but recently someone (don't know which platform) mentioned he/she only wants Tasmanian Devils if they add nocturnal behavior to the game/to these animals.
But that person also had some issues with RL zoos changing the wild behavior of Devils to please the visitors during opening hours.
So I don't know if it's nitpicking or a legit concern.
I have similar hangups about the kiwi, but in my case it's because I don't think any zoo (certainly not in New Zealand, which has the largest population of captive kiwi) has public kiwi displays that aren't confined to nocturnal houses, whereas a lot of zoos have daytime viewing for aardvarks, Tasmanian devils, and giant anteaters without any real trouble. For me the solution to any such problem is 'indoor lighting' (even with the kiwi, if they gave us indoor lighting I'd be perfectly happy), because you can use it to at least 'fake' a nocturnal house (blue, green, and red lights, hidden around plants, maybe some kind of big wall light that resembles the moon as well).
That said, I've worked with devils before, and there isn't really anything the zoo specifically does to keep them diurnal. If they want to hide away and sleep, then they aren't prevented from doing so. I've had to explain to people before that the animals don't operate on a schedule, and if they aren't there for people to see, the best you can do is leave and come back later in the day and see if you have better luck. Every second day they do a public feeding display which draws the devils out, but even then they aren't always interested.
