Just out of simple curiosity really.
I have a save file which is 5 years old which I played almost everything on, which is now about 11 MB & recently I started a new save where my sim is basically a photographer and that one is 24 MB within a few months what I did differently from the other save is that I took a lot of Digital photos (40-50) which is why I'm speculating that could be the reason for such an increase.
At the same time, I'm wondering if there are any other factors that can drastically increase a save file size.
