The Sims Online returns in a new form...
Announcing OpenSO alpha testing 🧪 Signups are open now!
OpenSO is a revival of FreeSO, a fan-hosted recreation of The Sims Online, upgraded with a modern foundation:
Runs on .NET 10 LTS with the latest MonoGame. GitHub Actions automatically builds client, server, and updated shaders for all platforms.
A C# launcher replacing the old Electron one, with an integrated patcher and self-updater.
Replaced the Mina.NET dependency with a rewritten networking and buffer stack supporting TLS end-to-end encryption.
Updated rendering pipeline: dynamic frame rates >60FPS, resolution scaling, new AA options, and optional post-processing effects for 3D mode.
New features: rebuilt Create-A-Sim with zoom & rotation plus larger icons; edit your Sim's gender, appearance, and skintone at any time from the Select-A-Sim menu; a Social Bunny NPC who shows up to help your Social need when your Sim is alone. 🐰
Fixed long-standing nitpicks, like the window scaling/mouse glitch.
Always free and open source, with no pay-to-win or donation perks.
OpenSO is early in development, so things may break or be rough around the edges. Expect frequent updates.
Player feedback will be crucial in shaping the game's direction. Once the foundation is tested under a real player load, the beta release can shift focus to new content & gameplay changes while staying faithful to the original game — as well as events, documentation, tools, and quality-of-life features.
The alpha provides starting funds of $100k to begin building. The testing world, Genesis, will be wiped for the public beta.
Signups are open now and public for anyone who wants to help playtest, report bugs, or contribute ideas and changes.
