inZOI Rivals The Sims: Sells 1 Million Copies, Teases Major Updates and Modding Revolution
May 9, 2025
inZOI, launched in early access on March 28, 2025, has quickly become a competitor to The Sims, achieving remarkable success by selling one million copies in its first week and ranking highly on Steam.
Despite its initial success, the game currently holds an 81% positive rating on Steam, with a decline in player count as many users await additional content.
This anticipation for new content has prompted KRAFTON to announce a series of updates aimed at enhancing gameplay and modding capabilities.
The upcoming May 2025 update will introduce a Mod project manager, tutorials, and new build mode features, along with cheat codes, an adoption system, and relationship improvements.
In addition, players can expect enhancements to the Create a Zoi feature and outfit updates, further enriching the gameplay experience.
KRAFTON will also release the inZOI ModKit via the Epic Games Store in late May, which will allow players to customize gameplay and share their creations through CurseForge.
This ModKit will include downloadable assets, plugins for 3D modeling tools like Maya and Blender, and compatibility with Unreal Engine 5, facilitating the creation of mods.
The first modding update will provide tools for creating outfit sets and furniture, as well as modifying game data, catering to the strong interest from mod creators.
As inZOI remains in early access, the development team is committed to transparency and is adapting its roadmap based on player feedback.
Future updates are planned for August, October, and December 2025, which will introduce new features such as pools, freelance jobs, and improved family tree capabilities.
By December 2025, most outfits will be moddable, allowing for deeper customization through interaction scripts and localization tools.
Game director Hyungjun 'Kjun' Kim has emphasized the team's focus on increasing gameplay depth and storytelling experiences, ensuring that player engagement remains a priority.
