I think that more animals will be a great Addition to the game.
I'm saying that there should be harvastable animals, like cows sheep etc.
They'll require food, maybe water, and after a while it'll give wool or milk or something like that to you if you use a tool of some sort (they spawn randomly in the world and you have to catch them with a net or something).
And may I shall add, an animal that kills other animals, passive or aggressive, only if they're his size or smaller.
Please tell me what you think about this suggestion!
