Ship Wrong, Part 2 (Patreon)

Even in real life, the "mystery" part of this game devolved into baseless accusing NPCs and ridiculous violence. Mystery games are some of the most notoriously difficult to pull off, especially if what the group is used to is more comedic stuff. In high school, a friend once tried to manage a horror campaign, but two players got frustrated and quit running from the monster, and the monster stopped. After that they realized it wouldn't attack because it'd kill party members before the game was over, and it was all downhill from there.
