My version Isle of the midnight sun

 Isle of the Midnight Sun

Backstory:
You always wanted to go on a cruise but your parents refused to pay for your trip.  After some thought, you got a job during high school and saved up to fund the trip yourself.  Two years after you graduated high school you were finally able to go on that dream cruise.  Things would take a dark turn when your ship runs into severe thunderstorms.  The ship had been tossed around hitting some rocks under the water which poked holes in the hull of the ship.  The ship started taking on water so the captain ordered everyone to evacuate to lifeboats. The severe weather tore apart the lifeboats. When your boat capsized you hit your head on the boat knocking your self-unconscious. You would later wake to the sun warming you and the sound of water hitting your legs as you lay on the edge of an island. It took you a few minutes but you realize you are stuck on an island alone. Now you must survive this new world.
Goal:
Survive and have 5 generations.
Setup:
Welcome to Isle of the midnight sun challenge. We can not build a custom world so you can use Oasis Springs or Brindleton Bay. Pick the largest lot in Oasis Springs or the island in Brindleton Bay. In the middle of the lot create a 10x10 lot and fill the rest of the area with water. Place fishing signs around the edge of your 10x10 lot. If you do not want to build one I have one on the sims 4 gallery under willowrazorclawz. You need to create a young adult with whatever traits you want. I suggest adding loner as one of them. I will be playing with no mods and all the packs. But this can be played even if you don’t have all the packs. After placing your sim on the empty lot you need to use the money cheat in order to build or download and place the lot.  I advise adding a fence around the lot so no one can get in or out. You will need to teleport your sim to the island. Reduce your money to zero with the money cheat. Set your lifespan to normal. That is 81+ days depending on your sim. In order to finish this challenge, you need to have 5 generations and the 5th generation needs to have a child that becomes a young adult. 
To start you can only fish and you need to sell what you catch. If you catch fruit you can plant it so you have food to eat. I have found that you can choose the skinny dip option in the water and it will raise your hygiene level. When you have enough money get a pee bush, bed and a bond fire to cook hotdogs. You need to also get a woodworking table and level up your skill so you can make a toilet, tub, mirror, 4 chairs and a table along with a side table and shelves.  Once you are married and have $1,000 you can buy whatever you want to make money, we will pretend it washed up on shore. If you have laundry day you need the wash tub and clothesline to wash your clothes.
You are only allowed to travel three times in each generation. You can go to granite falls, the jungle or to a lot of your choice. I suggest using granite falls since you need to learn herbalism and you need to collect stuff from the jungle and complete the collection. You will need to use the remedies that can be made using plants from granite falls. You will need a grill to cook them. If your sim has more than one child the youngest will be the heir. If your sim has twins or triplets you may choose who is the heir.  This challenge is over when your 5th generation has a child that becomes a young adult. You can not use any mods that will alter your gameplay, IE skills, mood, ect. You can use the money cheat at the start of the challenge, reset sim and moveobjects. Since you can build basements you can do that to expand if you reach the limit building up. 
Have fun and happy simming!
