So I've spent probably around ten hours exploring the new map so far, and so far I'm having a blast with it. I love all of the new species (the only ones I haven't hunted very much yet are the Magpie Geese and Banteng, but from what I've seen they look pretty good).
One thing I want to mention is that I think the devs nailed the overall feeling of vastness on this map. When you're traveling across the map, you get the feeling that you're really exploring a vast and expansive wilderness. This is something that the early maps like Layton and Medved did very well, but some of the newer ones haven't really captured that feeling of a vast wilderness. Emerald Coast does it very well though, the entire map has lots of variety and the individual biomes cover enough of the map that each of them feel big and very well fleshed-out. Not to mention that traveling across the map on foot seems to take me longer because of just how many animals I encounter and have the chance to hunt along the way. This map feels vast, wild, and truly full of life, and I love that aspect of it. The varied topography and the use of constantly changing elevations make it feel rugged and force you to take your time while traveling across the map, which is a breath of fresh air compared to maps like Mississippi that are almost completely flat.
I also like how the different biomes are just different enough from one another that different parts of the map are distinct and memorable. The most prevalent biome seems to be the open subtropical woodlands/grasslands, which cover a large portion of the map. However, there's also tropical rainforests, mangrove swamps, and even a dry outback area, and all of these areas feel connected while also being different from each other.
All of that being said, I have more feedback to give, which I will elaborate on in the thread.
