The problem lies in that "needing it to be nighttime" isn't really useful for anyone who isn't just straight up playing in a "I made my own character with their own backstory" sort of way. Which... isn't a lot of people who play video games, unless we're talking MMO's where you "role play" with other players... or tabletops... where you role play with other players.
Likewise, there's an issue in "what games will include for immersion, while keeping out other things".
Emulate Day and Night, but not days of the week, holidays, or even what happens in ACTUAL time passing (like people remembering your actions and reacting to your past actions). Yes, lets emulate time, but not what it would be like to be stuck in jail for 6 months for your murder spree. Yes, let's emulate time, but not what happens when you make NPC's late to their locations, or when you keep them up all night.
Put simply, the "time" thing doesn't exist for "immersion". It exists as a "half arsed idea" for one or two things and that's it. It exists because a game wants to include Stealth, pretty much universally. Or, because you have some mechanics where "the brothel doesn't open until it's night, same as the casino".
As for loitering... Yeah, sure, there's a way to "skip ahead", but should something like that REALLY need to exist in the first place? Can't wait somewhere "with enemies nearby" after all. Doesn't even matter if they can't see you and would never find you 'cause they never patrol the spot you're hiding in.
I, personally, find it difficult to "Role Play" when most of the systems you even mentioned aren't even "fleshed out" and are just an afterthought... like the version of how those things work in a 6 year old's doll house reality. I may as well be sitting at my kitchen table mashing action figures together at that point. That's my take on "eating food", "getting a buff for sleeping", "buying a house", "marrying", and "having children".
I can eat food? Nice! Oh, there's only like 20 things you can make. Thanks, I hate it.
I can sleep 8 hours? Nice! Let me devise a storyline in which it's important that I sleep 8 hours. Thanks, I hate it.
I can buy a house? Awesome! What can I do with it? I can't move furniture around? I can't install windows/doors where I want? I can't plant flowers outside? I can't wash dishes or anything? It's just a place to store my junk and "look nice"? Thanks, it's a 6 year old's doll house. How is this different from just playing pretend with children? Thanks, I hate it.
I can get married?! NICE! Oh, I can't just marry anyone? Has to be only specific people? None of them have personalities or anything endearing about them? None of them ever get angry? Have arguments? Have needs and desires of their own? Same with the children? So, they're just status sticks that exist? Thanks... I hate it.
I love Roleplaying. If games were better designed, i could actually do it. Instead, they put in random nonsense systems that are at most, 10% fleshed out for Roleplaying and only 3% fleshed out for people who just want to play the game, and do nothing else.
At which point I just go, "why bother? Spend your dev time creating something fun instead of whatever this abomination of terrible ideas was".
