- Development Gag: Not a gag relating to the development of the game, but to Back to the Future Part III. In Episode 1, Marty can find an old photograph of Marshall Strickland in Edna Strickland's home. Edna states that he had been shot and killed by Buford Tannen. Marty (who, of course, had been to 1885 when Strickland was alive and who was instrumental in Buford being sent to prison) states that he doesn't remember that occurrence. While there's an in-story reason for this (he wasn't there when it happened nor informed of the events), the joke is actually a meta-joke about how the scene depicting Strickland's death was cut from the film.
- Episode 1 references a gag from the aborted Number Two script, wherein Marty is arrested, and chooses the alias "Marty DeLorean" to get Doc's attention through the newspapers. In the video game, however, it's the other way around: Doc is arrested, and chooses the alias "Carl Sagan" to get Marty's attention through the newspapers.
- In Episode 3, George has a box of peanut brittle on his desk by the monitors. This refers to a deleted scene in the original Back To the Future where George displays what a wimp he is by being bullied into buying tons of peanut brittle. The only remnant of this in the final film is a shot of him pouring some into a bowl.
- Orphaned Reference: The names of Marty's grandparents are lifted from early versions of the script for the original film and the novelization.
- Talking to Himself: AJ LoCascio plays both Marty and Alt-1986!Jennifer's scumbag boyfriend in Episode 3.
- The Other Marty: The PS4/X Box One version has Tom Wilson reprise his role as Biff Tannen from the movies, having been Darrin'd by Andrew Chaikin in the original release of the game.
- What Could Have Been
- Biff's daughter Tiff was originally going to appear in Episode 3, but with Punk Jennifer there it was decided she was redundant. There is artwork of her here◊, and she eventually showed up in the comic book adaptation of the game.
- There were plans to give Doc and Edna a kid, but they decided against it, due to the ethical ramifications of erasing a person from the timestream.
