I've really warmed up to the idea of a recently extinct species pack as of late, to the point that it's now my dream "end of support" pack - just not if support ends this spring. If we got a South America revisit as well as a couple other packs rounding out the community's most desperate wants (baboon, secretary bird, tree kangaroo, pelican etc), I'd be fine seeing such a pack bring PZ to a close in a year's time:
(made this a couple weeks ago, been meaning to find somewhere to use it lol)
The main appeal of having these species in PZ rather than in another game like Prehistoric Kingdom is that, as animals from the modern era, I'd rather house them alongside other modern species than dinosaurs and mammoths and whatnot - things like having quaggas run alongside their fellow south African ungulates again, or dodos sharing an enclosure with Aldabra giant tortoises. A thylacine exhibit looks out of place in a park full of dinosaurs when it could be adjacent to the likes of Tasmanian devils and wombats. They compliment the already vast existing roster of modern species, while prehistoric species are distinctly "something different" and are far better served having entire games devoted to fleshing them out.
So yeah, while dinosaurs are a big no, recently extinct species would be something I'd like to see if we had enough development time - which we probably don't, unfortunately.
