First things first, you will need to replace the grass with snow in GF. You can find the mod here. If you want to go to town on this, edit all your townies in Household Management so they’re dressed for the weather.
Now you’ve done that, create your Sim. He or she should be dressed nice and warmly, and you should start from scratch. You want a Sim without any skills. Buy a lot in Oasis Springs or Willow Creek, and go straight to GF for 7 days. Once you’re there, using testingcheats on to reduce your cash. (money 50).
So, you’ve gone on vacation, and suddenly the weather has taken a turn for the worse. A freak snowstorm has hit, blocking all the exits from Granite Falls. The electricity is out, and there are no phones. Now you have to survive using only what you have. Learn to fish, and you’ll be able to cook on a grill. You cannot use your oven or fridge, as there’s no power. A cooler will help you store snacks and drinks, and the plumbing is still working. It’s taken the pump out that powers the shower though, so that’ll be down to a dribble. Let’s hope it doesn’t break- there aren’t any engineers that can replace it for you, unless you’re handy.
After day 3, all supplies run out from the Ranger Station. This means you can’t cook anything on your grill other than fish that you’ve caught. You can eat plants that you’ve harvested too. You now have to make it until day 7, when rescue will arrive and unblock the exit, allowing you to go home.
During this time, you’ll have to build your skills. The aim is to be at the highest level of 3 skills before you leave. Perhaps you’ll try Painting to pass the time, Gardening or Fishing to the highest level.
No skill cheats
No use of anything that requires electricity (only the lamps that would take batteries, candles or the oil lamp are OK to use light-wise)
Have fun! Be sure to post your pictures.
