I agree with most of that, but I would rather see more uses for the laundry room, like maybe helping the maids, and later sex in there. xDActually, this is another perpetual failure of sandbox games, and one HH doesn't avoid: unused locations. The laundry room probably shouldn't even exist, given how rarely it's relevant. But the shower, the hot springs, the garden, the bar, even Ellen's room: all ripe for content, all so terribly underutilized. The idea that about 90% of the time I check on the hot springs there's nothing happening is baffling. I don't necessarily mean from a game standpoint, I mean from a "what if this was real?" standpoint. People would be in the hot springs or the garden all the time. People shower at all hours of the day. Bars aren't just nighttime venues. Put someone there and give them dialogue. Later, when the stats are sufficient, give them events. It'll take a while, but it would make the in-game world so much richer.
Some of those are starting to get content, like Ellen's room, and the hot spring is starting to as well, including the dates, but like even now, we have girls hanging out there, but you can't do more than say 'hi'. It would be nice to have more. Especially once you start unlocking sex events with those girls, like Ann would always be DTF or whatever, Luci and Hana are kinky enough (though Luci should not be skipping work, lol), eventually the others...
Maybe find Lin cleaning in there, and sneak up behind her, or call her in there and ask her to take a break with you, and so on...
