Even though this DLC didn't break the pattern with the amount of animals, it stills seems to be modelled differently than the other DLCs. 3 out 4 animals have a very different feel from what we got already. The caiman being the last is also (most likely) coming with new animations (diving).
The overall theme fells more loose and even visits areas already covered in previous DLCs. I guess it can be compared to the Arctic pack (both being biomes/habitats rather than continents.) But this still feels different. The previous DLCs was more about adding a new area to your zoo, while this will more likely add to already existing areas.
Same goes for the scenery.
Also the exhibit animal seems to have a very different feel this time.
I can see this DLC+update open a lot of doors for future DLCs, and one of those doors could be DLCs with a larger number of animals.
It is easy to see Frontier really listened to the community this time, so I am sure they will continue to do so in the future.
Thank you Frontier!
