You will also need to be able to fight off wild animal attacks and maybe native tribes (not necessarily Human) that you encounter.
This is the city slicker's view of the wilderness.
Think Louis and Clark. Randomly attacked by natives? Nope, they were
helped by natives who were curious. Most had never seen a European before.
Likewise with animals. Most animals know better than to approach a human. The few that do are generally curious. The few "wild" animals that attack people generally do so because of either:
1. You stepped on her kid/ touched her kid/ gave her kid a snack, looked at her kid funny. Momma bear.
2. They're in heat (bull elephants come to mind.)
If I go to the nearest national park (Land Between the Lakes, about 20 minute drive) and wander randomly around, I'll be lucky if I see anything bigger than a squirrel. Not because there aren't animals larger than squirrels but because they're terrified of humans (and rightly so).
Quite contrary to games where the local fauna not only are aggressive but
hunt you down. This again has to do with the point of your game. Is it competitive or cooperative. Competitve games need to have constant cannon fodder for its players to sharpen their teeth on. Any game based around combat.
Um, hehe
