The problem with game design is often that there are features suggested that for example "add immersion" that create a lot of additional work and waste a lot of limited resources, but dont actually improve the game as a game.
Full simulation of a city is one of those. A shopkeeper who is open 24/7 and never moves from their spot may not be realistic, but its hella convenient for the player.
I totally agree!
It is possible to make a very realistic game.
Day and night cycle, complex scheduling of NPCs, weather with consequences, very tough resource management, realisticly constrained time, very limited capability growth during the game etc.
A treat for a small group of players, but I bet a lot on a big turnoff for the vast majority
