I could do without anymore spiders for a while. There are plenty of other lovely reptiles and inverts yet to be represented. I would welcome the introduction of proper diving mechanics and a select handful of charismatic aquatic critters currently kept in captivity, but would prefer we stick to only those kept with success in modern aquariums. No great whites, if orcas are a thing they should be incredibly difficult to keep and come with a lot of expenses and prestige. I think smaller cetaceans are common enough in zoos and aquariums that I disagree with skipping over them entirely. Expanding on the land and air based roster as well as the more common semi-aquatics before diving into the fully marine life would be a smart choice though. There're still so many classic zoo animals to cover that to do marine life before the roster is more complete would feel a bit premature. That's not to say I won't appreciate the animals regardless, but the timing of each species' release is important when you only get four habitat animals every few months. I like that we got a dingo, but I could've waited a year or two for it if the other option was a wombat, you know?
I'd prefer to see the living species roster expanded a great deal before any mention of extinct species, and even then I question if Planet Zoo is the appropriate platform for such an experience. However, the Planet games offer a degree of creative freedom not found in other games that deal with keeping extinct animals, so the premise does have some appeal. I would prefer to see a new Planet game conquer that theme rather than have it integrated into Planet Zoo. Mythical creatures in Planet Zoo are a no for me, it's just not the right setting for all the fantastic magic sparkle critters.
