I think it would be amazing to see a new reserve based on Norway or the Nordic region. The nature up here is absolutely beautiful — deep forests, fjords, mountains, tundra, and snowy valleys. It would make a perfect new hunting map called "Nordic Reserve".
The wildlife in this reserve could include:
Capercaillie
Willow ptarmigan
Black grouse
Hare
Ducks
Roe deer
Red deer
Moose
Fox
Beaver
Lynx
Musk ox (class 9) – new animal
Wolverine (class 3) – new animal
It would also be really cool to have a Transport DLC with things like a snowmobile, skis, and snowshoes. Skis and snowshoes could help you move quietly and efficiently through the snow, while the snowmobile would be great for covering long distances in the winter landscapes.
Another thing that would make the game feel even more immersive is more realism in animal behavior. For example:
Predators could attack or chase other animals while we’re watching.
Animals could have more natural reactions and movement.
When an animal dies, it could fall more realistically, tipping over slowly and maybe showing slight muscle twitches, rather than just dropping instantly.
