Trying this for the first time, and this is like a masterclass in how to do a grind-game right... You do something a couple of times, then move on to a variation, repeat. I like it.
But is it just me or does the evening meal seem completely broken? Even with a daily threat level of zero Rachel will just randomly decide to spank you, or she'll spank one of the girls while they're at zero (not the stolen homework one). My latest frustration was in sabotaging the navigation console; on a chore-free day at dinner Rachel said I didn't do my chores properly [wtf?] and sent me to chat with Susan, which progressed time past the point where I needed to change the console and broke the quest.
I mean, I assume I can try it again in a couple of days but that shit's still really annoying... It's as if Dinner Time just does its own thing, unrelated to your other choices.
