This is an amazing island world that has been updated for all EP up to Supernatural.

One thing I have noticed is that the Supreme Commander does nothing with the pet skills. I think that the Pet skills should be incorporated into the Supreme Commander. For the hunting skill at least, it should be very similar to the "Collect:..." command for regular Sims.

All of these worlds have been updated up to Showtime. They are in order from pretty good to freaking awesome. Hope you try them out!

I have had the school problems like everyone else, and one more; on some families, like the family in the Swamp and the single father family, the genealogy is cleared and they are booted from their jobs. So its just a bunch of unrelated people with the same last name and no job.
