Finally playing this due to the recent psn sale
Props for the realism but I don't think I can handle shooting animals in this game. Yeah the skinning is brutal as well but the hit reactions and noises they make when they're hurt combined with the graphics is too much.
It only took decades and decades but shooting a videogame character has finally legitimately disturbed me and it's for wildlife animals and not any humans.
A bit later on, you'll unlock an upgraded deadeye mode that highlights fatal zones on targets; makes it a lot easier to one-shot animals so you don't have to hear them whimper as they bleed out. Also be sure to use the right caliber of gun. If you're using the varmint rifle on a deer, you're not going to kill it cleanly in one hit regardless of where you shoot it. I do like that the realism of an animal struggling to survive serves as a really good incentive to get better about killing them humanely; I don't ever want to hear a coyote crying as it bleeds out again. Also, with some animals (things about the size of deer or sheep), you can lasso them, reel them in and you'll get a prompt to execute them with your knife; it's brutal, but also more humane than a bad shot.
I actually find myself apologizing to the animals I kill in the game. Last night I was doing stranger missions in the far northeast corner of the map, and I kept getting attacked by cougars; one of them flung my horse off a bridge into a lake and nearly killed us both. I had to shoot them and after each one, I said, out loud to nobody in particular, "sorry kitty." The game definitely makes you feel empathy for the fauna you encounter.
Or you could be like my brother (who, in the real world, is an animal-lover and spent decades working as a zookeeper and conservationist), and go full-on animal genocide mode the instant he picks up the controller. Literally one of the first things he did when he played was kicking a dog. He assures me he wasn't trying to; he wanted to shoot it. Like, damn dude, I've never seen this side of you.
