Yeah, I think for the most part starting with the Europe pack (so excluding the NAAP which wiped out half the top 10 with one release), we've been regularly getting 2 to 3 animals that were pretty highly requested. And actually, if anything, we're getting more of them starting with Grasslands.Oh yeah i don't mean that the 3 or 4 are in the top 10, but they are in the top of the list (top 25 most of them). Platypus and wombat were in the top 10 at the time yeah.
Twilight pack was an exception tbh... and it shows by the reception in this forum (myself included lol)
Grasslands got 2 in the top 10 but a wallaby was highly requested as well, and the caracal was in the top 30. The siamang in the Conservation pack pretty much was the choice for a gibbon species which was in the top of the list (which they added now with the Tropical pack).
Wetlands added platypus, small clawed otter and capybara, all of them high in the list and a non-ratite non-penguin bird for the first (and apparently last) time.
So yeah maybe not all animals in the top 10 will feature in one pack but looking at them you kind of can make a guess of the kind of packs they could be part of, and they are basically forests, deserts and tundra? (maybe).
Europe - Lynx/Ibex
Wetlands - Capybara/Platypus, and the ASCO was top 20 at the time, I believe
Conservation - Prezwalski's Horse, Amur Leopard, Siamang (subbing in those gibbon votes), we actually got really lucky on this pack since it's a scenery pack
Twilight - Wombat with both the Red Fox and Raccoon being in the top 30 (maybe even top 20?)
Grasslands - Maned Wolf, Emu and the Caracal and Wallaby were, IIRC, both top 20?
Tropical - Red River Hog, Lar Gibbon, Fossa, and like it or not the Sloth counts so that's actually 4 on that as well.
This is just my opinion, but I do think it likely Frontier is trying to front load these DLCS at this point, with 2, 3 or even 4 animals from with the top 20, while still including ad oddball and surprise animal per pack, if not more than one of those.
