Mutants & Masterminds is a superhero role-playing game written by Steve Kenson and published by Green Ronin Publishing. The current 3rd Edition, which also serves as the engine for the DC Adventures game, was released in 2010. It is highly flexible, point buy system that allows players to build any superpower they can come up with, from classic caped crusaders and vigilantes to cosmic entities and mystical sorcerers. The system it directly evolved from is d20 System (2000) Description Mutants & Masterminds' game mechanics use a highly modified version of the d20 System. All characters in this game, from heroes and villains to the average person on the street, are defined by eight abilities, basic traits each character has to a greater or lesser extent. Abilities tell you how strong, smart, and aware a character is, among other things. The abilities are: Strength, Stamina, Agility, Dexterity, Fighting, Intellect, Awareness, and Presence System Overview & Key Features The Single d20 Engine The system is a true d20 engine. The twenty-sided die will be the only one you will need for the rest of the game. Every roll happens with the d20 as the baseline and then various bonuses and modifiers are added or subtracted. Point Buy Character Creation There are no random rolls for character creation. Players are given a budget of Power Points based on the campaign's Power Level. Every ability, from super strength to immortality, has a specific cost per rank, enabling high amounts of character customization and forging your unique superhero (or -villain). Effects Based Power Design Instead of a list of hundreds of pre defined spells or powers, the game uses Effects. If you want a fire blast, a freezing ray, or a telekinetic shove, you simply buy the "Damage" effect and apply descriptors like "Fire" or "Cold". This allows for endless creativity in how powers are themed. The Toughness Save vs Hit Points The game completely eliminates Hit Points. When a character is hit, they must make a Toughness resistance check. Failing the check results in cumulative penalties. A minor failure causes a "Bruise" penalty to future saves, while a massive failure can result in being dazed, staggered, or instantly knocked unconscious. Power Level Caps To keep the game balanced, the Game Master sets a Power Level (PL) for the campaign. This acts as a ceiling that limits the maximum total of a character's attack bonus, damage, defenses, and skills. This prevents one player from being mathematically untouchable while others struggle to contribute. Victory Points and Heroics Players can earn Victory Points (formerly Hero Points) for roleplaying their character's complications, such as a secret identity or a specific weakness like kryptonite. These points can be spent to reroll dice, recover from injuries, or use "Power Extractions" to perform stunts they haven't officially bought yet.

A free, accessible, browser-based character creator and editable sheet for Mongoose Traveller 2022 — every roll cited, every choice logged, every character saved locally. Description Traveller Lifepath is a free, browser-based character creator and editable sheet for Mongoose Traveller 2022. It walks players through the full Mongoose 2022 lifepath — basics and species, characteristics, background skills, pre-career education (University, Army Academy, Marine Academy, Navy Academy), career terms with their full survival / event / commission / advancement loop, mustering-out, the post-creation skill package, and a final reviewable character sheet — without ever leaving a single browser tab.                                                              The tool offers three ways to set characteristics. Players who want the classic experience can have the site roll 2D × 6 into a pool and assign each value to whichever stat they like. Players who prefer their own physical dice can enter results manually; the site still tracks every DM, target, success/failure, and aging effect. Players who'd rather skip randomness entirely can use the included point-buy method (42-point budget, 2..12 per stat). PSI is rolled separately when psionics are enabled, and the Psion career unlocks accordingly.  /images/general-media/1778159165_rhvJ8xSn.png The character-creation rules are implemented as a typed effects engine — TypeScript discriminated unions with exhaustive switching — so every rule lives in one place and can be tested in isolation. The project ships with around 360 automated tests covering qualification, commission, advancement, aging crises, mishaps, life events, connections, the skill cap of 3 × (INT + EDU), pre-career education, and the Mongoose 2022 errata clarifications for Vargr and the Vacc Suit skill. A full audit trail of every rolled die, every applied DM, and every player choice is captured to a roll log that updates in real time. The post-creation sheet is a fully editable Mongoose-style character record. Skills, careers, equipment, weapons, armour, augments, connections, benefits, and free-form notes can all be edited inline; values save automatically to localStorage with cross-tab synchronisation, and the sheet is print-friendly (one panel per printed page, ink-friendly styling). Every character in the local library can be exported and re-imported as JSON for backup or for handing off between players.                                                      Two visual themes are included: a light "Little Black Books" look in the spirit of Classic Traveller, and a dark "Imperial" theme — plus a System mode that follows the operating system's light/dark preference and reacts live when it changes. Theme choice is remembered between sessions.                                                                    Accessibility is treated as a first-class concern. The interface meets WCAG 2.1 AA contrast requirements in both themes (verified by an axe-core audit suite that runs as part of the project's tooling), every interactive element has a visible keyboard focus indicator, icon-only buttons carry ARIA labels, and the layout includes a skip-to-content link for screen-reader users.            /images/general-media/1778159170_sbkOfhno.png Other features include undo across the wizard (rewinds to the relevant picker after popping a character snapshot), URL-based debug logging (?debug=1), the Connections rule for shared PC backgrounds, an aging-crisis path with medical-debt accumulation, and an honest "unofficial fan tool" disclaimer in every place it matters.                            The project is open-source under the MIT License, runs entirely client-side with no backend and no account requirement, and uses privacy-friendly analytics (no cookies). Bug reports, rules questions, and pull requests are welcome on GitHub. Links bytesbynelson.github.io - Live tool github.com - Source code github.com - Issue tracker / feedback

Threadfall is a campaign management platform built for live tabletop role-playing games. It records the session, transcribes speech in real time with speaker diarization, and turns the resulting transcript into a recap, a running campaign codex, and a live screen for the table, so the Game Master can stop taking notes and focus on running the game. The product was built by a Game Master frustrated with the gap between what happened at the table and what survived to the next session. Notebooks, spreadsheets, and post-session memory dumps consistently failed to keep up with multi-session campaigns where NPCs accumulate, loose threads multiply, and the party's choices weeks ago suddenly matter again. Threadfall treats the session itself as the source of truth: whatever was said at the table becomes structured, searchable, and remembered. /images/general-media/1779959619_6fDtbiNW.png Description What it does at the table During a live session, Threadfall captures audio, transcribes it in real time using state-of-the-art automatic speech recognition, and identifies who is speaking. A live screen, designed for a second monitor, a tablet at the table, or a shared display, shows the unfolding session in a clean, distraction-free view. The Game Master sees recent dialogue, current scene context, and tracked entities without breaking flow. What it does between sessions When the session ends, Threadfall produces a recap that captures what actually happened, character actions, key dialogue, decisions, and consequences: drawn from the transcript rather than from the GM's memory. It updates the Living Codex: a structured repository of characters, locations, factions, items, and plot threads that grows automatically as the campaign progresses. Entities are extracted, relationships are mapped, and the codex is searchable from the next session onward. Who it's for Game Masters running ongoing campaigns, particularly online or hybrid groups using voice chat, but equally useful for in-person tables with a recording device. It's system-agnostic: nothing in the product assumes Dungeons & Dragons or any specific rule set. It's been built and tested against D&D 5e and 5.24, but works equally well for Pathfinder, Call of Cthulhu, indie systems, and anything else where a group of people talks for hours and the GM has to remember it all. Free tier New users get two complete live sessions and recaps to try the product, with no credit card required. Founder rate Game Masters who subscribe during the launch window receive a Founder rate of $7.99/month for as long as they remain subscribed, including three campaigns, six AI sessions per month, the full Living Codex, and the live screen. /images/general-media/1779959641_ywkMFifG.png Technical foundation Threadfall is built on real-time speech-to-text with speaker diarization, large-language-model summarization and entity extraction, and a knowledge-graph backend for the campaign codex. The infrastructure is designed for the unusual demands of multi-hour, multi-speaker, jargon-dense sessions where the participants invent proper nouns on the fly. Independent and actively developed Threadfall is built by an independent developer who is also an active Game Master and player. The product is shipped iteratively, with bug fixes and features released as feedback comes in from the founding group of Game Masters using it weekly.
