1) Anvils for my stuck in time Sims who wants to make a living with a smithy.
2) Hunting for my far-off living in a forest cabin hermit.
3) A true immortality spell for your most powerful spellcaster.
4) More supernatural traits in the reward store (that's how I use them 9 times of 10, as developed powers for my Occult Sims).
5) Cars, trailers as placeable objects - no need to see my Sims drive with them, everything could remain at the lot), the trailer would even serve as a decorable mini-house which I then simply could move around as my Sims travels the world.
