In one of the points, the OP says that he attacked a deer and it didnt move at all or tried to run away. It stood there and took it till he died. I know alot of you seemed a bit disappointed (even though this was most likely caused by the early build of the game). But just for reassurance, i just saw a leaked video on youtube of gameplay from. . .PAX i think? Or gamescon. But anyways, in the video, i saw the player attacking what appeared to be a moose (could have been a deer), but when he started attacking, the moose/deer clearly began to run away (which looked pretty great).
So if some of you were beginning to get worried, dont. Must have been a bug or glitch.
