No Farming EP but Farming Kits, which one must be the first?

If they plan on kits for farming, I'd want them to add animals through kits instead of putting them inside the farming game pack. This way they could give us farming and give us the option to not purchase the animals, because some people don't want the animal part of farming. I personally don't mind them including everything in an EP, but I know some people wouldn't even get it if there were animals included.
