A full reimplementation of The Sims Online, using Monogame. While FreeSO aims to be faithful to the original game, it includes many quality of life changes such as hardware rendering, custom dynamic lighting, hi-res output and >2 floor houses. If you simply wish to play, you can install FreeSO and the original TSO files using our installer on http://freeso.org, and it will connect to our official servers.

FreeSO currently depends on the original game files (objects, avatars, ui) to function, which are available for download from EA servers. FreeSO is simply a game engine, and does not contain any copyrighted material in and of itself.

The Sims 1 via Simitone

FreeSO is additionally a base project for an ongoing re-implementation of The Sims 1's engine, Simitone, targetted mainly at mobile devices.

The content system, HIT VM and SimAntics VM included within this repo support both TSO and TS1 game files - meaning that TS1 will still run in a limited sense under TSO's UI frontend within FreeSO. Simitone fully restores TS1 gameplay by tying the neighbourhood and game systems together with a suitable UI frontend.

3D Mode

The FreeSO engine additionally supports an experimental 3D mode, which allows you to see the game from a different perspective. 3D meshes are reconstructed at runtime from the z-buffers included with object sprites. FreeSO also generates 3D geometry for walls and floors at runtime, and switches to an alternate camera with different controls when the mode is enabled.

The mode can be enabled via the launch parameter -3d. See the blog for more information. (http://freeso.org/the-impossible/)

Volcanic

Volcanic is an extension of FreeSO that allows users to view, modify and save game objects alongside a live instance of the SimAntics VM. It features a vast array of resource editors for objects - the most prominent being the script editor. It allows for easy creation of new objects, and debugging of existing ones. Volcanic also functions when the FSO engine has loaded TS1 objects and other resources.
