Question. How many 'real-world' minutes would make a Zoi's one full day feel just right?
In developing inZOI, we set out to create just about every component to closely replicate what you would experience in real life, including the distance needed to get from point A to point B as well as the physical sizes of different elements within the game.
However, one thing that cannot be further from replicating real life is our concept of 'time'.
In a game where you are able to play as multiple individuals (or multiple households!), requiring you to play the game for 24 real hours to get through one day of game progress, by any stretch of the imagination, cannot make for a great experience.
Thus begs the question, "How many minutes is just enough?" Currently, our development team believes it's '96 minutes', and the following paragraphs will explain how we got to that number.
Each morning, your Zoi will wake up, wash, change clothes, eat breakfast (or not eat breakfast- and starve 😬), and finally, go to work. With our Korea-inspired city of Dowon being really large (once again, replicating real life), we found that it takes a bit too long for a Zoi to leave their home and arrive at their workplace. In our early development stages, we tried to solve this problem by making every Zoi 'run' to their workplace. As you could imagine, that looked really silly on our wide camera view. One person came up to me, referring to the scene, mockingly congratulating me for perfectly replicating the 'busy city life of Korea'. I tried adding subway stations and even adjusted the Zoi's walking speed, but I just could not get them to stop being late to work. This was all when the game ran at 43 minutes for one day of game progress.
The solution that seemed to have worked out was when we made each day last 96 minutes instead. No longer were Zois rushed to their tasks as they went about their day, and the extra time made observing the everyday lives of Zois much more relaxing. You had time to take care of different needs for Zois to allow them a much healthier lifestyle, and because inZOI allows for many different interactions while you're out on the street, having that extra time really allowed you to better enjoy those aspects.
With all that said, we still couldn't ignore the fact that 96 minutes for a day of game progress is very long when you're talking about a simulation game. I can confidently say this because I personally enjoy playing different simulation games to this day, where many of them do not require more than just a few minutes for a single year of game progress to pass by.
For inZOI, we have it programmed where after one day of gameplay, every Zoi's age increases by one. To put that into perspective, having each day take 96 minutes of real time would require 96 hours of real time for a newborn Zoi to become 60 years old! Sure, we have a 5x fast forward option that if you were to play the game with only that option, the time would reduce to 19 hours and 12 minutes, but even that feels super long 😩
I want to know what you guys think. Is 96 minutes for one day simply too long? Will we need something faster than 5x speed? Or better yet, is there a brilliant solution to this problem that we were not able to think of? All of your ideas are welcome!
In my next post of 'Kjun's Concerns', I will get into a fan favorite: cars! More specifically, we'll discuss how vehicles should be utilized to achieve the most optimum gameplay in inZOI!

By increasing the decay rate, there were more HUMAN interactions, and since humans are social beings, whether the day lasts 48 or 96 minutes, make sure the Zois have a relatively fast decay rate to "force" players to engage with the world around them, whether with family or friends. This way, it’s also more likely that other Zois will interact more with each other, giving a sense of ACTIVITY. I did this with my mod Social Consequences for The Sims 3. Everything I'm mentioning here can be seen on my channel or my website (if you need a visual reference for these ideas).
