Oh my gosh, this is like my dream come true. ^___^
I think there should be a few axes along which a cowgirl could grow, like More human <---> More Anthro Ability to do manual labor vs. their ability to make milk, and so on.
I mean, the farm should be staffed entirely by cowgirls, so you'd have to allocate worker cowgirls, administrative cowgirls, and milk-producing cowgirls. As you got more cowgirls, you'd have to start juggling having them work out to make them stronger so they could repair and expand the facilities, but stronger cowgirls give less milk, and then there'd be the milking machines that would stimulate breast and udder growth, which would give more milk but lower their ability to handle clerical and administrative jobs, and so on like that.
Plus, there's the issue of how to get more cowgirls. You could hire them for a large one-time fee, or you could impregnate one of the cowgirls yourself, which would keep them from doing any job but milking for a while as they grew pregnant (But you'd get a boost in milk production for a while) but would eventually result in a "free" new cowgirl.
Of course, you as the owner would need to take car of how much and how often you "interacted" with your cowgirls- giving them physical attention might raise their morale and have them work faster, but do it too much and you might find yourself turning into a cowgirl herm yourself, and too much of it might make it so you're more dependant on them than they are on you, leading to you having less and less time each day to actually run your farm as you need to be serviced by your employees more and more often just to satisfy your libido and think clearly.
In town there would be a general store where you could buy basic goods, milking machines, tools for the worker cows, organizational amenities for the administrative cows, and perhaps an illicit drug or two to boost certain cowgirl "attributes" or perhaps even some for you the player if you like your cowgirl-ness...
A livestock store, where you could hire certain cowgirls if you find yourself, each with different strength, milk, and libido stats...
And perhaps evena pub, where you could meet various other animal-people and try your luck at a one-night stand that would enchance some of your own personal attributes to make yourself a better owner, or a better milker, or a better laborer, whichever you desire...
These are just all ideas off the top of my head, but a game that sounds like a cross between SimFarm and Nimin is about the best thing I've heard all week and can't wait to see what comes of it!
