Aside from the obvious ability to attack and/or hunt things, it would be cool to be able to encounter other werewolves or monsters, and compete with them and the humans. Also adding some sort of hunger mechanic to go along with hunting. Are there any really populated villages? I didn't see many towns or castles. As far as other interactions with the environment go, I would definitely like to see more things in the area around you, and some minor abilities like pouncing on enemies, slashing, or howling to scare them off.
