Video games are often thought to be about the quick hit or instant rush of dopamine gratification. In fact, many video games take a long time before they are enjoyable. It takes patience and investment of effort to start making an impact in the game world, and in many ways is actually hard, slow work.
Some games double down on this mechanic, using, as Brad Gallaway recently said "using the real passage of time passing as a way to progress the story or game mechanics. Without cheating a system's clock, they're meant to play out over long periods. Seaman was something like a month, and The Longing can be as much as 400 days."
The games in this list are designed to be played slowly over a large number of days. This includes games like Animal Crossing, which requires regular visits at particular times of day to progress your island. But it also includes games like The Longing, that test the player's willingness to wait long periods of time and limit their ability to accelerate progress. Or there are games you can play quickly, but require the real passage of time for certain aspects, like Nier Replicant, forcing you to wait 24 real hours between planting a crop and harvesting it
