How many worlds/save files do you have?

I have around 6-8 saves at the moment but each save is different. I have a vampire save from years ago and i refuse to delete my vampire girl so it sits there waiting for me. Heh. I have my main save which is a legacy and I'm on gen 7, then I have my other main save which is a rotation of my legacy founder's family cause I loved her so much and I had to try rotational and loved it, so it became my new main save. Haha. I have a 100 baby challenge save, a get famous save and a build save for practicing my building skills which isn't so good. I even deleted a few saves a while back cause it's been so long since I even played on them. I just can't let them go. >.<
