The Sims 3. I had to figure out how to disable OneDrive backup for my Documents folder, because Sims 3 insists on keeping your saves there, and somehow everything breaks if OneDrive tries to sync them. Previously I had given in and let OneDrive sync everything because Win11 nags you if you try to avoid it.

I also have to fiddle with processor affinity to get the game to launch, because it doesn’t play nice with modern processor architecture.

It still crashes a lot.
