Some games indeed. But I've also done art (graphics and music) and programming on Win 3.x with some of it being in proprietary file formats that can't be loaded by modern software. I could export music to MIDI and load that in modern software like Sibelius or Musescore, but I'd lose much of the notation. So instead I use the old software to have it on-screen or print it, then transcribe it.
