The new Ghostbusters game isn't the only Ghostbusters game to have ever been made. Ghostbusters 2 had an awful platformer, for example. And the original had a pretty decent game on the C64 and Spectrum.
That C64 game was actually one of the first I ever remember playing, and the entire I time i had a Commodore 64, I played the shit out of it. So it's nice to see the developers of the latest Ghostbusters game, Terminal Reality, paying homage to it in the above screenshot.
If you head upstairs in the firehouse in the new game, you'll see the terminal above displaying a weird message. Confused? It's the endgame screen you got in the old C64 game should you ever actually manage to finish the thing (pictured below). Which, for me at least, didn't happen very often.
