It does actually sound really good, @ThatsSoGallistra!
I'd love to see Bob's cabin. Maybe you can upload it to the gallery once it is finished. Is it surrounded by lots of leafy trees? I think Bob's future children need a tree house to play.
I'd like you to be able to finish that Legacy. As Roberta explained, there is no cloud saving for The sims 3, but I can explain you how to save your savegames so you don't lose them the next time 🙂
Your user files (saved games, screenshots, houses,...) are stored in a folder named "The Sims 3" inside Documents/Electronic Arts. Before resetting your computer, make a copy of that folder in a flash drive or external drive. Once you have finished the resetting, place that folder back in the same place.
If the resettings of the laptop are unexpected, make sure of making a copy of the folder from time to time, just in case.
If you want to change computers in the future, you can also move your saved games to the new computer. Just ask us 😉
Good luck, both for you and Bob,
Mai
