That's so cool.

I tried to make a whole alien family once, on Sims 2. But is was almost impossible because no matter how many male sims I got impregnated with a alien, it was the same Pollination Techinician, which made all the babies half siblings. I had to have a guy sim marry Stella Terrano, then have children with her. Then the children were unable to marry and have children with another alien sim.
