Were there any video games in 1940

No. Videogames came after the computer, which was invented in... Don't quote me on this but call it 1985. So no, with no computers videogames didn't exist, let alone the hardware required to run them.

If I asked this question, sorry, mam or sir. I was referring to more of a computer game which I found on-line; it might have used lightbulbs. Thank you.
