The Sims: 2 Open Source Clones Compared
Simitone describes itself in its own README as an alternative Windows frontend for The Sims 1, built on top of the FreeSO codebase — itself created for the online Sims Online — repurposed here for the original single-player game. FreeSims takes an unrelated engine-recreation approach and is cross-platform (Windows and Linux), with its own README explicitly stating it isn't intended to be an online game despite letting players visit each other's houses.
