I think that there should be hunting in the game so you could sell the pelts and eat the meat to restore health. There could also be missions that involve hunting down or observing certain deadly wildlife. I also think that there should be weapons that you can get from taking rare pelts or carcasses back to the tower. This hunting idea could also add things to your armor such as capes and other cloth or bone accessories. Maybe you could customize your personal vehicle. But overall I think there needs to be wildlife and maybe hunting.
