I'm sure there's a bunch if you go back to early arcade days or Atari/NES, like you said. But I had a hard time finding them with a Google search. Also if you count Flash/mobile games, there's a bunch there too. I would count in that instance. I released several Flash games back in the day where I did the code, sometimes art (sometimes I collaborated with an artist), sometimes I did the music too, and at least some of the sound effects (any that couldn't be generated with a synthesizer I purchased). And I released one game on iOS/Xbox 360 where I did everything as well. But they were tiny games compared to behemoths like Stardew Valley.
