Make a Skill be Hunting Dog Companion, like Rexxar's Misha (permenant)
Maybe a range upgrade Skill also...
Multiple Weapon options
Upgrades, but you need to take out time to cut trees (but you harvest fast)
Bears that hide in caves but will jump out to eat you
Birds to hunt also
You must hit attack to fire so that he doesn't auto-fire
Use Rifleman with the Crossbow attachment so you have bow
You can get rifle but have to buy it at town
Forest Rangers who try to stop you via Ensnare (long duration)
Big Deer who wanders, but will try to kill you, it drops extra stuff/points
A line of sight Skill, you start with poor sight range but then get GOOD
just a few suggestions
