It would be nice to get for the first time a big world as a "vacation" destination.
The Sims Castaway Stories used to have big lots (up to 80x80) that felt like TS4 open neighborhood.
It could be an expansion for Nature Living in a wild environment :
- New ways to fish (Harpoon)
- Climbing trees
- Figure out what is edible
- Create clothes with plants
- Build a shelter
- Deal with wild animals : make sure that they won't steal the food
- Make S.O.S. signals
In addition to this EP I would add Shaman Ability perks :
- Ability to communicate with animals and plants (socialize with cowplant)
- Summon spiritual animal (nature energy)
- Summon natural disasters
- Unlock Shaman magic staff
- Fertility Dance for plants produce more fruits, for a pregnant sim gets triplets or quadruplets.
- Baby Blessing : cure the occult state of a baby in a pregnant sim
- Worship and get blessing from an animal deity : Animal deities could be the one who give and recharge shaman power energy in exchange of offerings. For example a shaman could drain other sims energy as a gift for a mischievous animal deity.
