Options are allows a good idea, but compared to all the other things I want added to my gameplay options UI a dust slider is pretty low priority to me. I was fine with the original level with a household of eight, but, yes, anything outright broken should also be fixed.
I don't quite understand the too fast claim. It never seemed too fast time in the respect that it would always be too fast to me. It's like laundry and every other mundane chore in the game. It is bothersome and must be taken care of. That is the realism point, and I feel my real life house gets dirty too fast too but all you can do is get cleaning.
I do not see a lot of talk of it being unmanageable or twisted by other mechanics either, and it wasn't for me, unlike say how broken laundry is after hot and cold outfits and IL were added. Living in Sulani is laundry tartarus because Sims constantly go in and out of the water and leave piles upon piles for me to deal with-- Even when I am not playing eight Sims like I would prefer. I have also encountered bugs in general which will keep me from emptying hampers when I do loads of laundry and it just assures that you can never get on top of it. How many real life families have to have two full washer dryer combo set ups, a clothesline, and skeleton maid to keep their clothes washed?
