I must say I'm gladly surprised by the Dama gazelle! Iwant to see their pictures and I'm really curious about which subspecies has been chosen, as the nominate Dama is very rare in zoos, and the other two are more common (just in zoos...) but they aren't really know as Dama gazalle, but as Addra or Mhorr gazelles... I hope it's not just the species as a whole, as its subspecies have very different coats each other.
A good point about getting the black rhino and the dromedary is that we have another two species whose scenery pieces were included since the base game, finally! Which other items are still lacking its animal in the roster? The cobras from the Indian set statues, the tamandua from the South American bench...? And some jungle birds and coastal gulls?
It's true this is really a African ungulates pack in disguise, but I also think we have still room for even more of them! Gerenuk and forest buffalo are my most wanted but we all could think of another 4-5 more.
The strange things is that this "African" pack was really a great opportunity for getting a baboon or secretary bird... As some people has pointed, maybe they were left out because they would have been too much new rigs for the dev team, so it was better to throw a lot of easier ungulates.
Also, I find weird calling it just "Arid pack" (except for the rhino, they could have called it "Sahara pack"), being a 100% arid Africa pack and lacking any of the other greatly requested animals from the same biomes but different continents, like the blackbuck or the yellow-footed rock wallaby (and they wouldn't really need new models). I'll be optimistic and join the people suspecting that we will have them in future packs, so this is great news about the future of the game.
But what about animals like leopard tortoise or Barbary sheep? They are very similar to species already in the game, and also they are iconic from arid Africa... But very specially, what about Egyptian cobra, Moorish wall gecko, common or veiled chameleon, Greek or other Testudo tortoise...? All of them would have been better options for the exhibit instead of another viper. I don't really have complains about the chosen species, as it is a staple in desert reptile houses, it's just that the lack of chameleons, geckos and cobras is a sore point of the exhibit system at this life stage of the game.
All in all, I'm really happy about the animal roster of this DLC, there is not a single species that should be left out, and all the models we have seen so far look wonderful! But it raises questions about the choices of its naming and which the species were left out.
