I just finished my first rotation on my current save and saw that I have played 42 households! It got me wondering how many households other people play (per saved game).
Last time I counted my households there were a bit over 30 that I considered played. I have a limit on my favourites tab and I try not to let the amount of sims grow too high. It's partly because I've noticed I enjoy some households more than others and I don't want too many households that feel like extras.
