How would your sim live, like what would you put in the house and help fill their needs? Example; Cooking Lights Entertainment Etc... I know the waterfall and swimming in the beach fills hyg...
I hope they will add solar cells and wells and other things by and by. Perhaps a huge tank to collect rainwater.
Since the lot-trait can be placed on any lot in any world I might make little changes to make it suitable for the world that my sim is currently living in.
