New Content and Requested Changes to come Tuesday, December 23rd 2025!
The InZOI December Update is right around the corner! Sticking to their plans to improve core game mechanics and a focus on the player experience, rather than the extensive goals of the initial roadmap for the game, the devs of InZOI at Krafton have released a handful of videos going over intended changes and new features that will be added with the InZOI December Update. These plans range from UI changes to add more features or to improve existing ones based on player experience, to entirely new features and assets being added for the winter season!

This week, we focused on fixing and improving areas that have been lacking in inZOI. While reviewing your feedback, we also corrected a few things that, as a developer, I felt a bit embarrassed about. For example, we improved how Zois recognize and find the proper entrance when visiting a house, and we also fixed issues that made it difficult to perceive furniture slots. When developing a game, it’s easy for a developer to get caught up in their own ideas — “I’m sure this will be fun, and players will love it.” That kind of passion is what keeps us going, but sometimes it also makes us miss what the players truly need. I have to admit, I’ve been one of those developers too. But I’m lucky to have all of you. This week’s update includes new content currently in production for December, as well as fixes and improvements based on your feedback. Have a great weekend!

Hello everyone. I can’t believe it’s already Friday.
Today is our company’s anniversary, so I’m writing this update from home instead of the office. To be honest… this week was quite tough.
The multitasking feature we’ve been developing kept throwing unexpected technical issues at us, and it was pretty exhausting. When I say in interviews that “the inZOI team and I are new to this genre, practically beginners,” it’s not humility—it’s simply the truth. There’s so much to learn, and just as many hurdles to overcome. But even during hard weeks like this, I find comfort in watching the Zoi sitting at their computers, talking naturally with their families. It reminds me, “Right, this is why we’re making this.” And the group behavior system is actually showing better results than we expected, so I’m really eager to show it to all of you. Unfortunately… this week’s build behaved a little too strangely, so both new features will have to wait until they’re ready. This week, most of our work focused on improving core interactions—like having Zoi sit and face each other properly when they talk. We also began preparing winter outfits and Christmas decorations for December, so I’m sharing those with you first.
It feels like 2025 just started yesterday, but somehow we’re already nearing the end of the year. I’ll see you again in the next update in December. Bye for now~ kjun

It snowed a lot here in Korea today!
How’s the weather where you are? The inZOI team worked hard again this week— no, actually… we worked unbelievably hard. But~! We still haven’t been able to fix all the issues you shared with us… (Trust us, it breaks our hearts too)
Don’t worry, though! Once the December update is out, we’ll jump straight into a full improvement phase, gathering all your feedback and tackling it properly. We’re already collecting and fixing things one by one, so please hang in there just a little longer!
For example:
- Strong requests for slow dancing
- Feedback that infants should have no teeth, and toddlers should have 1–3 small baby teeth
- Fixing the unnatural behavior of vacuuming/mopping outside the house
- Making sure major in-game decisions are always the player’s choice, including options to disable automatic features (e.g., unwanted pregnancy/childbirth)
- Restoring the original Cat’s Eye plumbob
- Bringing back the old parking lot
- And many early-development quirks and features that still need proper tuning
We’ll keep addressing them one by one— slowly, but consistently! We’ll continue improving inZOI until we can confidently stand before you as a game that keeps getting better. – k.jun

Hello everyone,
It’s Friday. Once again, I’m only now able to share the update date—lately I keep forgetting things here and there. The December update is scheduled for Tuesday, December 23rd. I’m really sorry I couldn’t let you know a bit earlier. Today, I’m sharing a video with the latest development updates and this week’s results for the December patch. We’ve been working especially hard on the winter outfits this time. The event we prepared will run until January 31th, and once the calendar system is completed, we’ll integrate it properly. Our character artist also wanted to show off a piece created in inZOI, so I’ve included it as well. I hope you enjoy this week’s video, and as always, we welcome your thoughts and feedback. Because your feedback has been far more diverse and insightful than we expected, we’ve formed a dedicated team to gather and deliver your comments more effectively. They’ll be working closely with the inZOI team to ensure that none of your valuable suggestions are missed and that they make their way into the game. We’ll keep working hard toward the December update. See you again next week! – kjun
Are there any features you’re particularly excited about, whether they plan to release them on December 23rd or in the near future? Let us know! Make sure to follow The Sims Community for updates on InZOI and other life simulation games, and make sure to follow InZOI on their website and social medias!
Inzoi is (slowly) getting there and I’m glad they’re trying to add more stuff to the base game instead of charging $40 for weather or $40 for businesses. I also laughed at the kid hitting their younger sibling trying to act like nothing ever happened. Yeah sibling rivalry can get ugly and I’m glad they’re not trying to shy away from it akin to The Sims 4 which is too child friendly still (outside of mods).
Getting progressively better at pushups is something the sims 4 could have had ages ago. Would have been so much funnier watching random sims doing failed pushups at weddings
i missed the sims 3 snow
for a game in early access, their updates are just getting better and better, they are not shying away from listening to their community, I am just enjoying the ride.
