Ugh, yeah, with how big the roster is I can't believe that there are still so few small cat species! And small cats are certainly varied enough that there are several they can add without it feeling redundant or repetitive. Personally, I think the ocelot is just a no-brainer. They're common in zoos, and they're a great addition to South American and rainforest themed areas. And I think Pallas's cat would be very popular with players.
Also agreed that more South America and Oceania rep would be great. Players have been begging for the Tasmanian tiger since the start of the game. I'm hoping that with the addition of walkthrough exhibits, we'll get a lot of bird species from both regions. After all, that's where you get a lot of the most iconic birds. I. Want. Macaws.
Anyway. The red deer is a nice addition to the game. Very majestic-looking animal. Wish we got more of a shop upgrade than just some new balloon designs but whatever, I'm not gonna gripe about free stuff.
