I hate to have to say this, but I was played this save for almost a week in-game time. Now the game doesn't want to load the save, and even if it did I don't want to go through all that again, it was really boring. Everyone got covered in dirt and the toilet broke so no one could pee. But no one died, and I decided not to go against what I did this for, the Strawpoll was close, but also said no to manipulation. I failed once trying to spawn a kitchen fire; these guys refused to burn. Must be pay back for letting Corey die so early on. I did learn a lot about free will in TS4 though.
Sims can't starve because you can still get food out of a broken fridge, and if you're broke, quick meals are somehow free.
Sims can't use broken items. I mean, I'd sooner pee in a broken sink before going in my pants, but that's just me.
There's a lot of stuff sims won't do automatically. No one ever started painting, or crafting, or using the microphone. Nobody repairs stuff automatically, or uses the fire extinguisher.
Coffee. Even if it's shit quality, sims still love the stuff, almost more than food. I don't know where all the mugs came from, but they were all over!
The only specific skill object that was used autonomously was the punching bag. And the first sim to use it had the athletic trait.
Sims do start fighting on their own, but it takes a really low relationship score to do so.
There's more, but these are the big ones I can think of. Thanks so much for reading and I'm truly sorry it ended. In a little bit I'll upload the household to the gallery. Look for my Origin ID: thunderman75, item name 'Asylum Inmates', or #asylum or #aiexperiment.
