About inZOI
What Is inZOI
inZOI is a life simulation game published by the South Korean studio Krafton and built in Unreal Engine 5. You play as a creator rather than a single avatar, shaping cities, households and characters, then watching the stories they produce. Each character, called a Zoi, acts on its own free will, and the game simulates a whole city at once instead of one household at a time.
The draw is the mix of looks and simulation depth. Every Zoi is assembled from hundreds of personality traits, and their choices feed rumors, trends and even illness across the city. As an AI life simulator, it also folds generative tools straight into the game rather than bolting them on. Players who have wanted more realistic graphics from this genre usually point to that visual step up first.
The limits matter too. inZOI launched in Early Access on March 28, 2025, so parts of it are still rough, and the developers describe development as a marathon rather than a finished product. It also leans on generative AI, which runs on your own hardware, so weaker PCs will struggle.
Getting Started
- Buy inZOI on Steam or the Epic Games Store. The base game sells at a discounted Early Access price of $39.99, and a Mac version arrived in August 2025.
- Create your first Zoi in Create a Zoi, choosing from over 250 options covering face, hair, skin, body and outfits, or generate textures with a text prompt.
- Build a home with modular walls, roofs, stairs and furniture, then move your household into one of the two launch cities.
- Let the simulation run, take a job, build relationships and watch events unfold. Share what you make through Canvas, the in-game platform.

Key features
Realistic city simulation
inZOI simulates an entire city at the same time, not just the household you control. Zois act from their own free will and their personalities, so rumors, trends and illness spread on their own. Krafton says each Zoi is built from combinations of more than 400 mental traits, which is what makes their behavior feel less scripted.
Create a Zoi
The character creator is where most players start. You get over 250 options for hair, skin, physique, outfits, accessories and nail art, plus a facial capture tool that turns a webcam into your Zoi's expressions. It's deep enough to build a recognizable likeness, and simple enough to finish a character in a short session.
On-device generative AI tools
inZOI ships generative AI that runs on your own GPU. Type a prompt to make patterns and images for outfits, props and furniture, turn a 2D image into a 3D object for the home, or upload a video to create a custom motion. Krafton has said the models are proprietary and trained on company-owned assets and licensed material.
Build studio
The build tools use modular pieces like walls, roofs, stairs, fences, platforms and gates, so houses go up in a way that feels closer to real construction. Objects and furniture are resizable and recolorable, which lets you match a room to a look instead of hunting for the exact item.
Canvas community hub
Canvas is the in-game platform for sharing. You post characters, homes and story clips there, browse what other creators have made, and pull their builds and outfits into your own game. It's the social layer Krafton has put at the center of the experience.
Cities, careers and events
Two cities ship in Early Access, each inspired by a real-world location, with weather, streets and properties you can adjust. Zois take active jobs, build relationships, and run into dynamic events, so a save keeps generating situations instead of settling into a routine.
Motion capture and video
Facial capture uses a webcam to drive a Zoi's expressions, and video-to-motion turns an uploaded clip into an animation you can apply. Combined with the camera tools, you can stage and record short videos set inside your city.
Pros and cons
Pros
- Realistic Unreal Engine 5 graphics that set it apart from older life sims.
- Deep character creation with 250+ options plus a facial capture tool.
- On-device generative AI adds text-to-texture, 3D object printing and motion tools without extra cost.
- Canvas gives creative work a built-in audience and an easy way to pull in others' builds.
- The whole-city simulation makes events spread on their own, which keeps saves unpredictable.
Cons
- It's in Early Access, so some systems are thin and the build can be unstable during big updates.
- The AI features run on your GPU, so weaker PCs will struggle or miss them entirely.
- Launch content is limited to two cities, so the map variety is narrower than long-running rivals.
- Mods and deep lifecycle tools are still being added, so anyone wanting a fully finished sim should wait.
