The Sims

By community projects I mostly mean mods but I'd be interested to hear about anything adjacent.

For example Simitone is self described as

On modern operating systems, The Sims has a few nagging issues that make it less than playable. Simitone can be seen as a tool to improve the playability of your existing installation of The Sims. Here are some features:

• Playable in 3D - using a combination of models generated from the 2D sprites and created by the community.

• Download the mesh pack here!

• Custom user interface that works at modern resolutions. Working on a more desktop oriented interface.

• Improved graphical performance, support for high resolutions and refresh rates.

• Custom lighting - directional lights with smooth falloffs and shadows using generated 3D meshes.

• Volcanic, a program which allows you to examine, modify and create new game objects. (from FreeSO)

But I'm not too sure how the release of legacy collection will effect their efforts. The last release was on January 16th which was a couple weeks before the release of the legacy collection and a couple weeks after the end of FreeSO.

Another example is the Sims 1/2 starter packs by voicemxil on GitHub being taken down by a DMCA. Previously these were considered the way to play the original games in The Sims community.

Other than that some Sims modding websites or mods have gone on to specify that their mods are compatible but that's about as much as I've seen.
