Independence & trademarks
This website is not endorsed by or affiliated with EA or its licensors.
OpenTS3 is an unofficial community project. It is not developed, sponsored, approved or supported by Electronic Arts or Maxis. The Sims and The Sims 3 are trademarks of Electronic Arts Inc. Other names and trademarks belong to their respective owners.
References to The Sims 3 identify the game that OpenTS3 is designed to work with. They do not imply a partnership or endorsement.
Your game remains required
We do not endorse piracy, distribute pirated game files or link to pirated copies.
OpenTS3 requires your own legally acquired, installed copy of The Sims 3. Any packs or paid content you use must also be ones you own and have installed.
The mod reads the game files from your computer. It does not include The Sims 3 or unlock content you do not own.
What OpenTS3 provides
Any future OpenTS3 download will provide the engine mod and its permitted supporting software. EA’s game code and assets will not be included; the original game files stay in your own installation.
The Sims 3 and its content remain the property of their respective rights holders. OpenTS3 does not change the terms that apply to your game or additional content.
Free access & current availability
OpenTS3 will always be free. There will be no purchase price, subscription, paid builds or paid playtest access. The original game and any additional content are separate products that players must acquire themselves.
No public download is currently available. Private playtesting is underway; wider invitations will be announced through the community. OpenTS3 will be open source, but its repository is private during development. There is no announced date for the mod or public source release. The source release will cover OpenTS3’s own code, not EA’s game files.
Before any playtest or release, we will explain what is supported, what still needs work and how to get started. Development footage shows work in progress.
