Alright, opinion time!
I obviously didn't see this one coming, but that doesn't change the fact that I really like the animals in this pack!
Capybara felt like an obvious choice, and I'm glad to see it included. Red crowned crane is a marvelous addition, finally adding another bird to the mix. Also great to see the Asian Small Clawed otter, another famously requested animal for the game. The lechwe, water buffalo and the newt are all fine animals to be added. Now we come to the two animals of which I already expected would be controversial when I saw the announcement, the platypus and the caiman.
A good zoo game in my eyes offers a majority of relatively to very common zoo animals. The basis has to be there to make it work, and all in all I feel that Planet Zoo has (with some exceptions like birds and monkeys) a broad basis in that regard. Perfect? No, but I don't expect a game to ever be perfect. On the other hand, a good zoo game should also include a small variety of animals that are not common in captivity, allowing us to create both the more common types of zoos and outliers. In that regard, I firmly believe that animals like a platypus and the proboscis monkey have their place within the game, and that's why I think it deserves the spot in the DLC.
Now, most controversially, I disagree that the caiman is "unnecessary". Yes, we already have a caiman and when you look at the game on a short term basis your initial reaction might very well be "but we already have one?". However, long term speaking as someone who played ZT2 for 17 years, variation like this is a life-saver. I don't want to add the broad snoated caiman in every single zoo that I make, and being able to diversify is a major plus in my eyes.
Overall, this pack adds a lot of animals I like. Is it the birds pack that I wanted? No. But I feel like it's unfair to judge a pack based on what it could be, because in our minds, any pack could have been anything. So I always judge the pack on what is there and what it is, not what it could have been.
The minor criticisms I have are that I'm slightly disappointed to see that bathing is only added to the macaque and the capybara. I'm afraid it's going to be a bit limited to just sitting in water, whilst I was really looking forward to it being a more in depth (pardon the pun) behavior system that could be applied to animals like elephants. Now it feels ( and again, pardon the pun) a bit shallow.I sincerely hope that more animals get it in the future and that it is more than just sitting in the water.
One other criticism I have is that I'm quite disappointed to see that the pantanal scenario map has the standard rainforest backdrop again. This was an excellent chance to give us a non-mountain backdrop and I feel like it's a missed opportunity.
Overall, I think the update and the DLC are nice additions, although I do still feel that both are a bit light on content compared to the updates in the past year. I was kinda hoping that the DLC would spice up the update a bit, but alas, it's not the case. However, keeping in line with judging a pack for what it is and not for what it could have been, this feels like an all round good addition to the game.
