The GM Is a Cheating Bastard

Go To

"The only reason a DM rolls dice is for the sound they make."

...but sometimes, they're our cheating bastard.

While Video Games are run by a cold, inhuman computer, Tabletop Games can be more flexible because they spring from the mind of living, breathing Game Master (who may or may not be cold and inhuman). The Random Number God's power can be broken, plot-devices can appear to save or bedevil the players, encounters can suddenly become harder or easier and, depending on whether or not the game is Serious Business, in-jokes can abound. There are even specialty "Dungeon Master's Dice," which are more-or-less the same... but blank on every face!

This can be a blessing if the players want to send their adventure screaming Off the Rails or eschew the usual Fighter, Mage, Thief party structure for something more flavorful. A nice cheating bastard can make sure things stay fun for the newbies and maybe give the characters a little help when they've had a run of bad rolls. Unlike that bastard, the computer, a good GM will mainly fudge the rules to preserve the vastly more important Rule of Fun and Rule of Cool.

However, this trope has a dark side.

If the nice GM takes things too far, the players' victories can seem preordained and hollow. And Pelor help you if a Killer Game Master is a cheating bastard... you might run up against a band of omniscient orcs that fight like they were trained as Spetsnaz. A sudden Ass Pull might save his Villain Sue, or you could miss a twenty-foot-long dragon because you Failed a Spot Check. If a particular player gets annoying, their character might get a Pit Fiend dropped on them. (Hell, the entire party may fall victim to falling rocks if the GM's feeling especially vindictive.) And remember those blank dice? A computer can't feel spite (as far as we know), but you may yet come to miss the Random Number God.

But take heart! It can be nice to Earn Your Happy Ending, and it certainly feels good to have your characters triumph in this GM's mad world. It can often be more fun to be killed by this GM than to survive the entire adventure of a GM that's too nice. And always remember, the GM's word may be absolute in the game, but kicking a excessively jerkassish GM out is not unheard of.

In-universe Examples:

    Anime & Manga 
  • In Yu-Gi-Oh! and its Yu-Gi-Oh! (first anime series) adaptation, Yami Bakura is this for his Monster World tabletop board game. As Game Master he initially cheats at his dice rolls to continue giving himself super criticals, until Yami Yugi counters with his own dice cheating and forces Bakura to implement a rule that forbade both of them from spinning the dice. However Bakura still manages to cheat, by using specially prepared dice with souls trapped in them. However, he then gets thwarted by the good Bakura who steals the dice and makes them roll the worst possible combination. His final act is to seal a part of his own soul into a pair of dice in an attempt to kill Yugi and his friends, but the good Bakura uses his own soul to possess said dice and destroy them, finally defeating Yami Bakura.
  • Sword Art Online has two examples.
    • Akihiko Kayaba, who became a Killer Game Master when he trapped all the players in SAO, had their avatars permanently deleted on death, and also killed players who died in-game in the real world. He appears in-game as Knights of the Blood Oath guildmaster Heathcliff, using his administrative privileges to keep himself alive long enough to be the eventual traitorous Final Boss. Subverted in his last duel with Kirito, though, when he did away with his GM advantages (he was good even without help from the system) and accepted his defeat with elegance.
    • Nobuyuki Sugou, a Corrupt Corporate Executive who traps the minds of many SAO players after that game is cleared for Mind Control experiments and is GM of Alfheim Online. When Kirito reunites with Asuna, he uses his GM privileges to use an unreleased, overpowered spell to bind them and modify Kirito's pain absorbers while torturing him. He is ultimately defeated when Kayaba's virtual ghost allows Kirito to use his administrative privileges and pull this trope on Sugou.


    Fan Works 
  • Played for laughs in the Skyhold Academy Yearbook installment Love is a Mystery, when the teachers run a session of Gatehouses and Ghouls. Varric, who is the game master, is teasingly accused of (very lightly) cheating to make the game a bit easier for Bethany's character. He doesn't deny it, but no one really minds it either.

    Films — Live-Action 
  • The Gamers:
    • Nimble is basically able to change the rules of the game at will. His antics include Back Stabbing a powerful enemy with a ballista, and Retconning his own death three times.
      Nimble: Did I say walk down the corridor? I meant sneak down the corridor.
      Nimble: Did I say sneak down the corridor? ...I crawl down the corridor. Inch by inch. Looking for traps.
      Nimble: [to Rogar, the party tank] OK, actually, you go first.
    • Meanwhile, Newmoon isn't allowed to use basic race features or shoot the badguy before he stops jabbering.

    Live-Action TV 

  • In Find Us Alive, Klein fudges her rolls to keep Love's wolf companion Balto alive during the group's game of Outer Kingdoms. When forced to reveal the number she actually rolled, it's a killing blow to Balto.

  • Destroy the Godmodder:
    • Due to the meta nature of the game, the fact that this is one of its founding tropes is lampshaded every once in a while by characters. The best part is that its revealed in-universe that some of the characters are aware of their own fictionality, even after the point in the second main game when the game master is pulled into the game and a good number of the players decide to get revenge.
    • And then amped up when Doc Scratch kills twinbuilder (the GM at the time) and takes over the game temporarily, abusing his GM powers, even up to the point where he becomes a boss.note 

    Tabletop Games 
  • The rules of the parody RPG HoL explicitly state that the "HoLmeister" is allowed to cheat whenever he wants to. Period.
  • This is also the case with Paranoia, to the point that GM Fiat is a listed equipment type.
  • Actively encouraged in Ravenloft during the opening segment of House on Gryphon Hill. If the players haven't played the original Ravenloft, they are put up against Strahd. The DM is encouraged to do whatever it takes to kill the players, including summoning banshees and fudging dice rolls. And then they wake up

    Video Games 
  • In CrossCode, Gautham is this. He appears in the game as the Blue Avatar and uses his world-editing privileges to give some enemies unbeatable amounts of HP. His avatar can also fly.
  • In Inscryption, the GM will fill his entire side of the field with powerful bears if you are beating a boss too easily on the first try, since he expects you to lose at least once to each boss. While difficult, it is still possible to defeat all of these bears, which will cause the game to continue as usual apart from the GM having glowing red eyes for the rest of the run. Amusingly enough this is the only time he cheats; even his Final Boss getting utterly invalidated by mechanics he didn't consider in especially stupid manners is something he allows despite his annoyance.

  • The infamous "Dungeons and Dragons" sketch by The Dead Alewives (you know, "I'm attacking the darkness") has the Dungeon Master eventually reveal that he fudged a roll to avoid killing a character whose player showed admirable gumption.
  • In Spoony's Campaign, during one battle where Skitch's character Garret is downed and fails a death saving throw, Spoony fudges it in order to make up for an unexplained AC penalty that came up (and was apparently a glitch in the character builder program). Or at least he tried, but Skitch was kind of spacing out and missed what was happening, causing Spoony to rescind his charity.
  • In the Counter Monkey episode "Botchamania", Spoony describes a game where the players were suffering from a streak of bad luck and he tried to help them out by giving them more Saving Throws than they should have rightly gotten under the circumstances. Unfortunately, their luck was so unbelievably bad that they kept rolling Critical Failures, meaning Spoony's charity was just giving them more opportunities to screw up.
  • XP to Level 3 discussed this in his homebrew rules that he uses. While he largely discourages cheating or fudging dice rolls, he openly admits that he runs by the Rule of Cool; XP argues that if something sufficiently impresses the DM, or if the player is willing to make a Heroic Sacrifice in the name of doing something, the DM should allow it. The example that he uses is a Paladin trying to save a party member from death, and the Paladin bargaining with XP (as the DM) to sacrifice some of his Paladin levels to do it. While there's no mechanic that says the Paladin can do such a thing, XP allowed it to happen.

    Western Animation 
  • In the Dexter's Laboratory episode "D&DD", we see Dexter as a Killer Game Master, cheating at dice rolls and throwing badly unbalanced encounters at his party for the express intent of "winning". He is then contrasted with Dee Dee, who instead runs the game with the goal of providing an engaging and empowering experience for everyone, and even designing encounters so that every member can contribute. Dexter naturally resents the fact that his friends prefer Dee Dee's playstyle over his.

Alternative Title(s): The GM Is A Cheating Bitch, GM Fiat
