Willy Wonka and the Chocolate Factory is like a Saw movie for kids: it matches grisly fates to the sins of the children who enter the factory. I needed all or most of those grisly fates to be represented in the adventure: blueberrification, being boiled alive in chocolate, being shrunk and stretched, uncontrollably floating, plus a bunch more of my own design. All of them weird and gory and absolutely deadly.
They were one of the first things James Raggi took issue with.
While LotFP adventures have a reputation as being really deadly, he wanted BitC to be for 1st level characters, and specifically new players. All my listed damage was way too high, and all my poisons too lethal. His point was along the lines of “How can characters get weirded out by these if they’re dead?”. He suggested toning down the damage of the adventure significantly, and instead focusing on these poisons and effects inconveniencing players or making them rethink how they play.
This turned out to be a genius suggestion, because it provided a clear through line for the rest of the adventure. Few things in the final draft of BitC are designed to explicitly kill. Instead, they’re designed to unsettle, gross out, and inconvenience players. Body horror carries with it the threat of death, but it’s more about the perversion and grossness of life than it is about death.
This is why death is boring. “How can characters get weirded out by these if they’re dead?” Answer: they can’t. They laugh or shrug or whatever and roll up a new character. “What’s next?” they ask.
And understand, I’m not denigrating that kind of play. If a rolling series of grizzly deaths is what gets you and yours excited to play, more power to you. But if you’re into body horror, the joy isn’t in the death, but all the stuff that leads up to it. It’s the inflation, or the bulging of the eyes and the appearance of gill-like slits along the neck, or the way the xenomorph squirms within your belly as it grows. It’s in the way the body devolves, or turns traitor, or evolves in sudden terrible spurts.
And sure, the victims of body horror often die (Aliens franchise) but sometimes they devolve (“The Shadow over Innsmouth”) or evolve even to a point beyond fleshy existence (Akira). The real challenge for a DM running a game based on body horror is keeping the horrors and transformations new and fresh. Too much of anything gets boring after a while.
And this same principle largely applies to nearly any campaign; death is anticlimactic. It’s got no answer for, “What next?” except shake off that old character and everything they’ve been through up until now, and start a new one. It violently forces the player out of the fiction and thrusts them head-first into the realm of mechanics (though skilled players can hop right back in again). All the work the group has done to build up tension and interest in that character and their contacts is suddenly chopped off. Death is, in terms of fun, expensive.
Which isn’t to say it should never happen. The fear of death creates wonderful tension in a game. As a DM, killing an NPC you love early on is good way to let the players know you mean business. (Hey, it works for GRR Martin and J Whedon, right?) But it’s vital you keep in mind your themes. Death is rarely the best way to support those, and defeat that doesn’t involve death can give you entire new avenues to explore.
