Visual Pinball X ("VPX", see https://www.vpforums.org/index.php?app=downloads&showcat=51) runs community authored recreated tables with ROMs dumped from the hardware. The physics engine has good performance and authenticity.
Another project, Visual Pinball Engine, ported the C++-based physics engine to Unity (https://github.com/freezy/VisualPinball.Engine) through its DOTS & "HPC#" (C# with manual memory management extensions) approach. Unity adoption means you can play high fidelity tables right in your browser (https://appmana.com/watch/pinball).
Then there's commercial platforms like Pinball FX and people building VPX rendering in VR.
It's maybe the biggest simulation scene I know of. The community fills many niches. Rigs of Rods & Beam.ng for the idea, "Microsoft Flight Simulator, but for cars." XMage & Spellsource for "Magic the Gathering or Hearthstone but you write your own cards." Unreal Engine for Fortnite is a big entry for the open world community authored content dominated by Minecraft, with submarine stuff like Facepunch's S&box (think Garry's Mod 2.0) coming up.
