How many worlds/save files do you have?

I have my main save, which I’ve been working on for over a year now and is my pride and joy, my test save where I try new things I wouldn’t do on any other save, my Get Famous save I don’t really use anymore, my building save where I build stuff and have test families to make sure it’s suitable for the gallery, and my Strangerville save I haven’t played on for a while.
