I vote CAS Preferences over chemistry in Likes/Dislikes. It would mean more clothes get tagged a specific style, which would make sorting, randomizing & selection go a lil faster.
CAS is an enjoyable core feature, but a huge time suck.
Setting up households, sorting by color & style 'speeds' things up. But not many styles and even less clothing is tagged as any style. Especially non Base Game packs. A huge plus for Dream Home Decorator; it tagged more Build/Buy items as a style.
I'm a rotational player. And I'd love my townies/households to stay 'in character'. At the very least, the favorited ones.
Do I endure the eyesore or fix randomized nightmare outfits? City Living festivals, Get Together events, Seasons cold weather (vampire gear). Not everyone needs an eyeball or nose ring.
