I was thinking today i love sims alot and i was thinking this as a possibility. Sims 3 Up, Up, and Beyond. This expansion pack would revoulve around Alien's and there Home world. The most major edition is Alien the new life stage. Alien abductions would some times take the sims to either Mothership (Sub-Neighborhood) or Simix (Alien Homeworld/Neighborhood). Simix would be filled with cool Sci-fi Alien homes and of course alien families. Alien abductions would sometimes get males (and females) pregnant. If Unleashed is real then some Alien animals running around Simix. This is just a sample tell me what you think
