What do you mean by last one is a long shot? I don't see a last one, just 2 suggestions.
Oh yes I was thinking about both of these things though!
Hunting creatures I'm not sure on how I would do it yet, because I've yet to find a combat system style thing I like a ton in audio games. But I'm going to test out some things.
As for farm animals those are great suggestions though! If I really wanted to be cool, I could have it be you raise a hunting dog that helps you hunt monsters some how! Them barking in the direction of the thing you want to hunt maybe? Could be fun!
