You know they made a game like this......they called it the Sims and it sells millions of copies every time they bring out a new one.
We should also have to go to the bathroom regularly.
...and make sure we eat plenty of fiber, but not too much or we'll have to even it out with rhubarb to avoid constipation.
...and make sure we don't drink any milk, because we're probably lactose intolerant.
...and make sure we don't get our socks wet, because that would really svck.
...and make sure we wash our clothes at regular intervals, or we'll be shunned by the community.
...and make sure to shave, brush our teeth and clip our toenails regularly.
Seriously, get a grip! It's a game, at some point the fun of it has to triumph over complete realism.
