the sims 2 legacy collection: How to reset game to default

I want to know this for the Sims 1 version to, all my pets in the town are called Luna... but when I reinstall it's just the same game. 

Uninstall the game, find the EA Games > The Sims 2 Legacy folder and delete it (usually in Documents), then reinstall

yeah i did it already but when I reinstalled, everything is still the same, not reset anything 🥲

Are you trying to reset the neighborhoods and the households? This page on The Sims wiki talks about resetting the game, where you just need to delete some folders:

Apparently there isn't an easy way, but there does seem to be a workaround, according to the wiki:

yeah I found this wiki but it for the ultimate collection, it's a bit difference I don't see that folder😅

Are you using the game through Steam? If so, I had this problem and I managed to fix it by removing the files while the game was still installed. While on the game's Steam page in my library, I went to Manage > Properties > Installed Files > Browse... and deleted the "The Sims 2 Legacy Collection" Folder. I then uninstalled the game through my computer's program removal software. After reinstalling the game, The sims 2 reset to its default.

Unfortunately, If your issue is through the EA app,  I don't know how to resolve it.

I hope this helps

I also came across another option that might work for you. If you go into Documents -> EA Games -> The Sims 2 Legacy and delete the Neighborhoods file the default Neighborhoods file will generate when you launch the game again.

Edit: Do this while the game is still installed.
