I tend to play to the point I'm oversaturated then I need to play a different game or not play games at all. Then I come back to it, usually with a different scenario in mind.
I've been playing my American sitcom save a lot recently, but I feel invested in that one so I definitely don't plan to abandon it, as there is a lot more I want to do. I'll put one of the families through Christmas week with aging off to finish off the current year, then switch them to a 4 week calendar instead of 2, so I can resume from a new point when I'm ready.
I have also been craving the sims in a save I made regarding my book series though, so it might be time to go back to them soon. I spent far too long over the weekend looking for very specific CC for my main character.
In the meantime maybe I'll take a break from gaming, or play some Crusader Kings III.
