* StillbornFranchise: Two expansion packs were planned, but sales plummeted when ''VideoGame/HalfLife1'' came out a short time after ''Shogo''.
* WhatCouldHaveBeen: Not only were there two expansion packs planned, the game was originally going to include a flashback to Sanjuro and company's childhood (you can see a few seconds of it in the opening movie), in which your interactions with the other characters would determine how your dialogue with them unfolded later in the game.
