The bout engine that resolves every HM92 match relies on GDScript staying correct through constant iteration. GUT, an automated testing framework for Godot built by Tom "Butch" Wesley, is one of the tools that makes that possible.

HM92's entire card system is built on a base by CaféDraw and SnoopethDuckDuck: the physical card frame and star-rating icons that every technique, tachiai, and joker card in the game still uses today.

HM92 runs on Godot, a free and open-source engine built by a global community of volunteers and maintained under the MIT license. Every scene tree, every script, every export template we use exists because people built it and gave it away.

One of the creators behind HM92's ambient and background music passes is HoliznaCC0, a prolific musician whose entire output is released CC0. The name is the license: zero restrictions, zero requirement to ask.

One of the creators HM92's audio work has leaned on most is haberchuck, whose synth-driven, city-pop-adjacent tracks form the largest single body of music we've built the game's sound around.

Part of HM92's collection-card work leans on a pixel hanafuda deck, the traditional Japanese flower cards, by Raechel V. It's one of the cleanest pixel hanafuda interpretations we've found, and exactly the reference a sumo game drawing on Japanese card culture needs.

Before HM92 had a single original sound effect, it had OpenGameArt.org open in a tab. The site has run since 2009 as a clearinghouse for free, license-tagged game assets, art, audio, music, made by a community that just wants games to get finished.

If you've played an indie game with a crisp UI click or a clean menu chime, there's a decent chance it came from Kenney. He's one of the creators HM92's interface audio has drawn on, built with the open-asset community, credit where it's earned.

Running a heya in HM92 costs money, and the game tracks it for real: a finance ledger you manage alongside a reputation score that gates everything from recruitment quality to how the sumo world treats your stable.

HM92 has a character-event system running quietly under the surface: an EventManager that registers, pulses, and triggers dynamic events tied to individual rikishi, then persists them through saves so your heya actually remembers what happened.

Every technique, tachiai, and joker card that exists in HM92's live pools is browsable in one place: the Card Library, an in-game encyclopedia that reuses the same card widget and tooltip as the bout itself, filterable by type.

You don't build a heya from a static roster in HM92. New recruits generate procedurally and arrive through an actual recruitment layer, gated by your stable's reputation, so a struggling heya can't just poach a prodigy out of nowhere.

Pro sumo runs six divisions at once, from the top-flight Makuuchi down through Juryo and beyond, all fighting inside the same 15-day tournament. HM92 models that split, not just one ranked ladder but several running in parallel.

Every rikishi in HM92 gets a shikona, a ring name, generated the way real sumo names work: built from meaningful character combinations, often tied to a heya or region, not just a random string of syllables.

Sumo's ranking system, the banzuke, is the sport's oldest piece of infrastructure. Every wrestler on the board is ranked, division and number, east or west, and the whole list gets rebuilt after every tournament based on who won and lost.

HM92's bout system is a deckbuilder. Every rikishi carries a persistent deck of techniques, tachiai, and jokers, and jokers are where the personality lives: close to 80 of them, spanning mental traits, archetypes, demographics, and situational effects.

Tokyo is not a uniform city. Its 23 wards each have a distinct character. Asakusa keeps Edo craft and temple culture; Marunouchi is corporate towers; Ryogoku smells like chanko and tournament press; Ginza is white-glove department stores. In 1992 the contrasts were sharper.

In martial arts, kata is the practice of forms: prescribed sequences run correctly, over and over, until movement becomes instinct. The discipline isn't novelty, it's the quality of attention in each repetition. Sumo's daily shiko, teppo, and suriashi follow the same logic.

Sumo is deeply Shinto. The dohyo is sacred space. The salt thrown before a bout is ritual purification. The shimenawa rope above the ring marks it the way one marks a shrine. The referee's costume echoes the robes of a Shinto priest.

In 1992 the PC-98, NEC's PC-9800 series, was Japan's dominant personal computer. It ran business software, early visual novels, and management games. The look is distinctive: structured menus, crisp limited-palette graphics, boot sequences that narrate what the machine is doing.

Sumo has always produced archetypes: the technician who reads opponents, the immovable wall who grinds everyone to the edge, the showman who plays the crowd, the hungry climber who fights every bout like a promotion audition. Different heya breed different styles.

A management sim with a walkable city has two problems: the management layer and the world layer. They have to talk to each other cleanly. The city should respond to what's happening in the stable, and the stable should reflect what you do in the city.

City pop, the smooth Japanese pop and R&B that peaked in the late 80s and early 90s, is the sonic landscape of HM92's Tokyo. Taeko Ohnuki, Mariya Takeuchi, Tatsuro Yamashita. The sound of the economic bubble: warm, aspirational, a little melancholy in hindsight.

Chanko-nabe is the communal stew rikishi eat in bulk to build and keep their size. It isn't one recipe. It's a tradition with hundreds of regional versions: chicken and dashi, seafood and miso, pork and soy. Each heya has its own.

Pro sumo runs six tournaments a year, one every two months. Each is called a basho. It lasts 15 days, and it ends with a completely reshuffled ranking list. Every rikishi fights once a day.
