Sorry for the barrage, I just had a lot of pet thoughts recently.
1) Did villains end up with plots to steal pets?
2) Can you give animals to people in order to earn their favor?
3) If people see an animal they like is hanging out with you in adventure mode, will their improved mood make them any more amenable to talking with you or traveling with you?
4) Before the big wait, will people talk more about their favorite animals, colors, foods, and art styles?
Right now you can parse out if somebody likes a tone of music based on their responses, which is WILD, but it's hard to get much of a personality picture in adventure mode even with extended interactions since they don't need to eat or anything.
5) Can you ride a horse that isn't yours? If you jump on a horse that isn't yours, what does the horse think? What do people of the village it belongs to think about it? What about if you didn't tell it to leave but just sat there, just having landed on someone's horse? Is that like being seen in sneak mode?
6) If you start with a bunch of cows with your adventuring group, are they all pets, or can you just have a herd's worth of food to live off of through the barren winter months?
7) Where does it draw the pool of embarkable adventure mode animals from? Could that pool be expanded through the concentrated efforts of the player, either in adventure mode or through domesticating in fortresses?
8 ) Can adventurers enact the cattle raid style missions they can currently do if they retire in a fort?
9) What if, hypothetically, an adventurer leapt onto a dragon? What if it'd been tamed by a fortress, or was a dragon of a group not at war with the player's civilization? What if it *hadn't* been tamed by a fortress? What does the dragon think about all this and could it ever end well for the player with an extremely good animal handling roll and some foreplanning?
