@JGoldman10,
Wreck It Ralph had references to classic arcade games, but the film as a whole took place in two fictional games that were made in the 2000s. Nearly all of the references were on screen for a few seconds, with Q*Bert getting at least 2 minutes of total screentime.
There is also the book and later film Ready Player One, which relied on 80s pop culture for its plot. The book, though, featured more 80s video games as essential parts of the story, like Joust.
There is also Jumanji: Welcome to the Jungle, which is set inside a early 90s game cartridge, and heavily features video game cliches.
Besides, it is very common that studios produce 2 or more competing films with similar premises. It has happened many times spanning decades. Last year had Captain Marvel (from Marvel Studios) competing against Shazam (formerly known as Captain Marvel).
2015 had three major spy films: Mission Impossible 5, James Bond: Spectre, and The Man From UNCLE. Oddly, all three films are part of franchises that started in the 60s (though the James Bond books were published in the 50s).
