Maybe that would be a good type of final pack - not so much a pack to wrap up some of the most wanted remaining animals, but ..something akin to an epilogue. Lower effort, still part of the game obviously but not something that people should get their hopes up to include completely new types of animals. Just something to give us a slightly deeper choice than what we have now, for these more high profile species.
Not directed at you on this part, but I should stress that again. The higher profile species. The bigger names, the traditionally more popular or iconic animals. I know that what's more popular will vary from person to person but thinking of it more of a whole. I'm not saying every species we only have 1 representative of should get another. I think as a whole player base, we're probably okay with 1 Armadillo, 1 Cassowary, 1 Pangolin, and so forth.
Also
@RedPandaReggie that's a lot of animals on that list, over 100, and these are just the priorities? I'm not saying you can't put that out there, I'm just saying you're almost certainly going to have to rely on mods to get anywhere near close to that. Then again, keep reaching high, it's how progress and if you don't ask, you won't get.
