Exactly this. Anyone who has played a game that really does use a 1:1 day/night cycle to real life (like the Gen 7 Pokemon games) can tell you how big of a pain in the ass this really is. Ever had to wake up at 5 in the morning just to evolve a Lycanroc? lol
And before you say that one can just adjust their system clock, games that use this 24-hour cycle can punish you for manipulating it, again like Pokemon Sun and Moon, and I think Animal Crossing: New Leaf locks you out of time-sensitive events for a certain amount of time for doing so as well, but I haven't touched it in two or three years.
I didn't know this real day/night cycle has been used in a game already, what Pokémon games use this system?
