- What Could Have Been: Thanks to The Harvester Show, many tidbits about the game's background, original concepts and Dummied Out content have been revealed to the general public. Some of those include:
- Not only was Mr. Pastorelli in the Barber Shop supposed to talk, he was also going to be semi-aware of Harvest's true nature, even warning Steve about it in Italian, hinting at the possibility that he could be a real person like Steve and Stephanie. This idea was abandoned probably because it would have given away too much about the twist to Italian-speaking players.
- The Wasp Woman was supposed to have a larger role; during the task when you're going to steal the cloth from the firemen, you could deviate their attention by setting her house on fire, in which would allow you to break into their home and steal the cloth. This action was mentioned many times in the script, but for unknown reasons was removed.
- Some places, such as DNA's Diner and the Firemen's Department originally had extra rooms which you could enter; in the latter's case a bedroom with five beds in them, where a cutscene could be triggered that would hint at Sheriff Duane being Ambiguously Gay. Both rooms were removed because they were deemed unnecessary.
- In the original teaser for Harvester, the characters weren't Full Motion Video actors, but instead were either 3-D Models or drawn, and Steve has a more southern accent.
- Word of God says that Mr. Pottsdam puts Stephanie's tampons in the toilet as a sort of symbolic denial. He hates that Stephanie isn't his "little girl" anymore, and he rejects that symbol of her womanhood. That's never seen in the game, however.
