Fun fact: most first-person shooters can also be summed up with "click on the right pixel".

I suspected as much. It's no Citizen Kane, but is a movie that is very much a product of its time. For better and worse. But I would say it was near perfect 80s entertainment with broad age appeal at the time. Seeing it for the first time decades after release... I can see how one might be underwhelmed.

Amusingly, for a while I was also considering Ghostbusters as one of my favorite bad movies (not as in "so bad it's good", but more ike "yeah, it's just a minor gimmicky movie, but super enjoy it"). I have revised my judgement since. I now think it's really objectively briliant on all levels. My "personally truly enjoyable sub-movies" bag is still full, but Ghostbusters itself is now in a different category.

Now for style and substance in games, I expected something a bit different.

For what you mean with it, my frst thoughts go to "Evil Genius" and, even more, "Ghost Master". But are a bit clunky, a bit clumsy, a bit missing their target ("Evil Genius" is easier if you just ignore its array of available traps, "Ghost Master" ruins its psychological gampeplay with timed objectives), but their concept, sincerity, energy and joyfulness are just too enjoyable to really let these gameplay failures ruin the fun.

Still, I expected a discussion about "art" vs "gameplay" (vs "philosophical content" ?). Given how close videogames can be to art, how often we play for an atmosphere -or a narrative- more than a challenge, I'd say all these aspects can easily compensate each others.
