Florida, Northern Alaska and Texas would be fantastic hunting locations, and here is my reasoning:
Florida can benefit from even more waterfowl, being a second map to hunt alligator, and allowing for the introduction of florida turkey!
Northern Alaska could be a snowbound map with Dall sheep, Musk oxen, Arctic fox, Snowshoe hares and potentially Polar bears.
(basically a reboot of whiterime ridge from classic)
Texas can be a fantastic reserve as it is home to many game ranches with imported species from different locations (similar to parque fernando), and it could also include Coue's deer.
