FreeSO is an open source reimplementation of the engine used in The Sims Online. It was created as a fork of Project Dollhouse, as the simulator's code and emergent networking drove the project in a different direction.
It features a near full featured implementation of the SimAntics environment, which reliably runs all objects in the game. FreeSO currently supports online play using isolated "lot servers", which function without a "city server", but this is a temporary measure to allow users to play the game while it is in development.
Extra features of FreeSO include native support for resolutioms above 1024x768, GPU acceleration, 5 storey lots and more complex lighting. Other improvements are planned but will be optional.
