The general evolution of tabletop roleplaying games in the last couple of decades has been towards streamlining and speed, abandoning a lot of the number-crunching minutiae of 1970s and 1980s games in favor of simpler and easier systems.

''Hackmaster'' goes running in the other direction. Screaming.

This is the game played by most of the characters in ''ComicStrip/KnightsOfTheDinnerTable'', which is a sort of [[AffectionateParody barely-veiled parody]] of ''DungeonsAndDragons''. A few years into the magazine's life, its publisher Kenzer began to branch out into making games of its own, and licensed the rights to the first two editions of ''Advanced Dungeons & Dragons'' in order to make a real version of ''Hackmaster''.

The result is a fully playable if murderously complex fantasy tabletop RPG with a healthy dose of in-jokes and meta-humor from the "Knights" comic strip. It reads exactly like the game from the strip, complete with bizarre rules, typographical errors, and lengthy digression-filled rants from Gary Jackson that read like something between a highly defensive, neurotic man speaking out on behalf of his work and the Unabomber's manifesto.

Take first edition ''AD&D'', with its weird class balance, gender issues (e.g. the infamous "strength cap" for female characters), huge number of charts, and idiosyncratic rules, and add a "building points" system, merits/flaws, a huge critical hit table with thousands of potential results, and a ridiculous variety of monsters. It deliberately eschews streamlining and handwaving; you roll for everything, you keep track of everything, and cutting corners is not allowed. It's a bit more coherent than first edition ''AD&D'' ever was, but it jumps on any chance it has to add more charts and tables.

The first actual edition of ''Hackmaster'' was published in 2001 [[UnInstallment as the fourth edition of the game]], with the "Garweeze Wurld" from the "Knights" strips as its standard setting. In 2007, Kenzer's agreement with Wizards of the Coast expired, preventing them from using any copyrighted material from ''AD&D'' in ''Hackmaster''. The game soon switched over to ''Hackmaster Basic'', which contains all original material, and the original rulebooks for ''Hackmaster'' are out of print.

! Tropes include:

* AffectionateParody: If you played first or second edition AD&D, ''Hackmaster'' is one part nostalgia trip to one part reminding you that you were crazy to play a game that was this unnecessarily complicated.
* {{Defictionalization}}: The original ''Hackmaster'' books do absolutely everything they can to indicate to a reader that they're exactly the same books that the Knights are using to play the game in the comic strip. This includes obscure rules, typographical errors, Gary Jackson's rants, and the results on the critical hit/fumble tables.
* EverythingTryingToKillYou: This is the game system of choice for people who subscribe to the theory that the GM's job is to try to kill player characters. One critical hit can abruptly kill or maim a PC, everything is shockingly expensive, and there's a deliberately large number of monsters that appear to exist entirely to pop up as random encounters in taverns, towns, or ''latrines''.
* FanFlattering: In the introduction to the 4th Edition Player's Handbook, it said of Hackmaster players, "We're not ordinary we're Extraordinary.'' The introduction to the Game Master's Guide praises the reader's "spirit, drive and determination to rise to the challenge."
* {{Gorn}}: The cover art for most volumes and modules of ''Hackmaster'' is shockingly violent if not incredibly detailed, typically featuring monsters and [=PCs=] alike getting hacked to bits. The ''Hacklopedia'' volumes, the ''Monster Manuals'' of the line, tell a story with the cover art about a luckless adventuring party getting killed to the last man, then being brought back as zombies to menace their torch-bearer.
** They're also [[TheBadGuyWins The Monsters Win]], especially in regards to the Hacked versions of classic [=D&D=] modules. For example, [[TheKeepOnTheBorderlands Little Keep on the Borderlands]] depicts the [=PCs=] being annihilated by the owlbear on the inside cover.
* HonorBeforeReason: An "honor" system exists in ''Hackmaster'', and it's just as easy to game as it is in the "Knights" strip.
* IntimidationDemonstration: The monk class's Intimidating Display and Really Intimidating Display abilities.
* MinmaxersDelight: The game encourages you to tweak a character as far as you can by spending "building points," taking flaws, and doing everything possible to get even one more bit of combat potential onto that sheet.
* ThatOneRule: A bunch of "one rules" from ''Knights of the Dinner Table'' are in effect in ''Hackmaster''. The most notable of them is that sewing needles appear on the weapons chart and do 0.125 damage, just as in a "Knights" strip.
