I´m pretty new to the sims 4 and I´m wondering if it is possible to create a new househould/game without it co-existing with my prior made household, and also without the original sims having died or being gone.
Just press new game and it will start as if you've never played before
You can either start a new save file in the start screen if you don't want your original sims in your new game, and then you can switch between save files to play your different houses. Alternatively you can create a new household entirely and move them into a separate lot. If you don't want your original household to continue aging up, make sure you turn that option off in the Game Options (Menu>Game Options>Gameplay>Auto Age Played Sims - select no).
Hope that helps and welcome to The Sims!
