Savage Worlds (2018)

Gamma World is a post-apocalyptic science fantasy roleplaying game created by James M. Ward and Gary Jaquet, first published by TSR in 1978. Over more than four decades the game has been rebuilt from the ground up seven times by nearly as many publishers, and the most recent overhaul came in 2010, when Wizards of the Coast released a stripped-down, card-driven edition built on a pared-back version of the Dungeons & Dragons 4th Edition engine.  Where D&D sends heroes out to save a kingdom, Gamma World drops mutant scavengers into the wreckage of a shattered Earth to fight over technology nobody left alive still understands. Description Gamma World is gonzo by design. A character isn't built so much as collided into existence: two randomly rolled Origins get mashed together into one being, however little sense the combination makes ("I'm a Radioactive Yeti," to use the game's own example). From there, characters spend the session drawing from decks of mutation and salvage cards that shift constantly - the powers a character has at the start of a fight are rarely the ones they'll have by the end of it.  Combat is lethal and character turnover is high, so the game leans into its own chaos rather than fighting it: sessions play fast, tonally silly, and are built to be picked up and put down in a single evening rather than carried across a long campaign.

Delta Green is a standalone tabletop roleplaying game of modern conspiracy and cosmic horror. Originally a supplement for Call of Cthulhu, the current standalone edition was published by Arc Dream Publishing in 2016. Players take on the roles of federal agents or contractors working for a secret, illegal organization dedicated to containing supernatural threats and covering up the existence of the Cthulhu Mythos to protect the United States. The system it directly evolved from is Call of Cthulhu Description In Delta Green, the horror is not just about monsters; it is about the toll that a life of secrecy and violence takes on the human soul. Agents juggle their high stakes investigations with their crumbling personal lives. They must navigate a world of bureaucratic red tape, government conspiracies, and sanity shattering entities while ensuring that no one, not even their own families, ever finds out the truth. The game is famous for its bleak tone and focus on the cost of the "Great Work." System Overview & Key Features d100 Percentile System The game uses a familiar percentile dice engine. Skills are rated from 01 to 99. To succeed, you must roll equal to or under your skill rating. If the tens and ones digits match (a double) and the roll is a success, it is a critical success; if it is a failure, it is a critical failure. Bonds and Domestic Ruin Agents have Bonds representing their relationships with loved ones or colleagues. When an agent suffers Sanity loss, they can choose to project that trauma onto a Bond to reduce the loss. This mechanically represents the agent coming home and taking their trauma out on their family, slowly destroying their personal life to stay functional in the field. Sanity and Adaptation The game tracks three types of Sanity loss: Violence, Helplessness, and the Unnatural. If an agent experiences enough Violence or Helplessness without breaking, they can become "adapted," making them more resilient to those triggers but less capable of maintaining human empathy and Bonds. Lethality Rating Instead of rolling many dice for heavy weapons like assault rifles or explosives, Delta Green uses a Lethality percentage. If the player rolls under this rating, the target is instantly killed. If they roll over it, the weapon deals a fixed, significant amount of damage instead. The Home Phase Between missions (Operas), players play through a "Home" scene. They must choose how to spend their limited time: fulfilling responsibilities to maintain Bonds, seeking therapy to recover Sanity, or practicing skills. Choosing one often means neglecting the others, leading to a downward spiral of isolation. Special Training and Agencies Character creation is deeply rooted in real world professions. Whether you are a CIA Case Officer, an FBI Special Agent, or a CDC Epidemiologist, your profession dictates your starting skills and the federal resources you can leverage during an investigation.

Traveller 2E is a sci-fi tabletop roleplaying game system, that was published in 2016 and updated in 2022, by Mongoose Publishing. It involves the characters adventuring through star systems, engaging in (space) exploration and engaging in battles both on ground and in space. The system it directly evolved from is classic Traveller (1977) Description The characers in Traveller can be humans, robots, aliens or of a genetically engineered species. Each character is distinguished by their occupation - whether they are a civilian, military, a noble, a young cadet or a veteran. Each type comes with their own strengths and weaknesses. To further expand on the sci-fi aspect of the game, some characters are prone to extra-sensory abilities, such as telekinesis, telepathy and others. System Overview & Key Features Lifepath Character Creation When creating their character, players roll to determine their character's background, education, and career history. Characters will acquire skills, allies, enemies and physical injuries. No Classes or Levels Characters do not have traditional classes, and they do not gain experience points to level up. Progression is entirely material and narrative. Characters improve by acquiring better gear, installing cybernetics, buying larger starships, and finding lucrative trade routes. The Trade and Commerce System A massive part of the game involves interstellar economics. The rules provide deep, robust systems for buying speculative cargo on one planet and selling it at a profit on another. Players must factor in fuel costs, jump drive maintenance, and life support while managing their massive starship mortgage. Lethal Combat Gunfights are incredibly dangerous as the characters have very low health pools. These are directly tied to their physical attributes like Endurance, Dexterity, and Strength. A single shot from a laser rifle can instantly incapacitate or kill a character, making armor and cover absolute necessities. Hex Crawling and Subsectors The game provides incredible tools for the Game Master to procedurally generate entire sectors of space. Using a blank hex map and the core rulebook, you can roll up planetary environments, government types, law levels, and starport qualities to create a completely unique sandbox galaxy.

Encounterra is a free, browser-based D&D 5e (2024) combat encounter simulator that helps Dungeon Masters test and balance encounters. Users can build tactical maps, customize characters and monsters, and run encounters repeatedly using strategic AI to explore outcome statistics, combat logs, and replays. Its public version uses SRD 5.2.1 content and is independent and unofficial.

Forge Steel is a community-developed, locally-hosted web application and digital utility designed for Draw Steel, the cinematic fantasy tabletop role-playing game created by MCDM Productions. Developed by independent community members during the game's playtest phase, the application functions as a lightweight encounter builder and combat manager. It is specifically built to assist Directors in organizing game data and tracking real-time combat statistics during a session. Description Forge Steel serves as a digital toolkit for preparing and executing combat encounters in Draw Steel. In contrast to cloud-based alternatives, Forge Steel relies on local browser storage. This means the application does not require users to create an account or rely on external servers to save their data. All created encounters, customized monsters, and campaign notes are stored directly within the cache of the user's web browser. This architecture prioritizes data privacy, offline accessibility, and fast load times, though it requires manual file exporting to transfer data between different devices. System Overview & Key Features Local Storage Architecture The application operates entirely within the user's web browser without communicating with a backend database for everyday use. Because it utilizes local storage, no login credentials are required. This ensures the tool remains highly responsive and can continue to function even if the user loses their internet connection during a game session. Encounter Construction Directors can use the tool to design combat encounters by selecting monsters from an integrated database. The application automatically calculates the total Encounter Value, allowing the Director to balance the difficulty of the fight against the level and size of the player character party. Active Combat Tracking During gameplay, Forge Steel provides a dashboard to manage the flow of combat. It tracks essential Draw Steel mechanics, including monster Stamina, current initiative groups, temporary status effects, and the accumulation of Villain Power. This centralized view reduces the amount of physical bookkeeping required by the Director. Integrated Bestiary The application includes a searchable bestiary containing the official monsters released during the Draw Steel playtest and early access periods. Directors can quickly filter these creatures by role, level, or faction, and view their complete stat blocks, abilities, and passives directly within the app. Import and Export Functionality To mitigate the limitations of local-only storage, Forge Steel includes manual data management tools. Users can export their prepared encounters, custom bestiaries, and campaign data as JSON files. These files can then be saved as backups or imported into Forge Steel on a different computer or browser, allowing for manual cross-device syncing. Homebrew Integration Directors have the ability to manually input and modify monster statistics. This allows users to create custom adversaries or tweak existing official monsters to fit their specific campaign needs. These custom entries are saved locally alongside the official bestiary.
