How long do you guys usually keep playing a save file for?

My longest running save was Desiderata with Downtown, Bluewater Ville, the family bin sims and my own sims, 2009 - 2015. However, I didn't play continuously, there were two long breaks and a couple of smaller ones. But even so, this game was something special that no other Desiderata playthrough I'll do after it can ever compare to.

Normally my rotational saves last about two years, and I always have smaller side saves that last between a week and two months.
