How many played sims do you have in your game?

Did not check in a while, but I assume 750.

I have all residential worlds bar the fairy world, and play them all on rotation in my 10 years old save. Some houses I just stop by for a few hrs every 3rd year, so not all of those sims get my full attention. With so many worlds I've started to ponder about implementing restriction to my game, like a max number of residential lots (or units) per hood. Not there quite yet, though, but I really should try reducing the amount of sims...
