I don’t have any old saves anymore, deleted them for various reasons. I have some saves for different challenges when I feel playing them. But I have three which are growing to big ones. First is my ultimate decades challenge save, where first gen is all gone by now and second gen is starting their families. This one I mostly play with the main family, but check out side families time to time too. Other one is my big rotational save I started last year. I created one young adult Sim for each world with different careers and plans for future. Just playing second round with this one and need to add sims for couple of the newest worlds. Then last weekend I started a new one I begin to combine my favorite sims from different saves I don’t feel playing anymore. I think this might became one I put aging off and rotate more loosely playing the family I feel at the moment.
