Sounds really cool. I'll be happy to play this new version.
As for comments? I think the biggest thing I want (without having played the updates) is a save system and a stats system. Being able to come back to a game would be really nice, and having a score to tell me say... "Most calories in a day" "Most money earned in a Livestream" and "Number of Baby's/Number of pregnancies" stuff like that.
Can't make difficulty comments just yet because, as I said, haven't played the new game. I think streaming once a week seems fair? With it not being the focus of the game that's what I'd suggest.
