Rollplay

Roll20 is the most widely used browser based virtual tabletop in the world, launched in 2012 following a successful Kickstarter campaign. Developed by Riley Miller, Nolan T. Jones, and Richard Zayas, it was designed to break down the barriers to tabletop gaming by requiring zero installation and offering a robust free to play tier. It remains the industry leader in total user base, hosting millions of games across nearly every imaginable tabletop system. Description Roll20 is the "everyman" of virtual tabletops, prioritizing accessibility and ease of use. Because it runs entirely in the cloud, players and Game Masters can start a session in seconds from any modern web browser. It features an integrated marketplace where users can purchase official rulebooks, adventures, and art packs that integrate directly into their campaigns. While it offers advanced features like dynamic lighting, its primary appeal is its massive community and the simplicity of its "pick up and play" nature. System Overview & Key Features No Installation Required Unlike many of its competitors, Roll20 requires no software downloads or server configuration. The Game Master simply creates a room on the website and shares a link. This makes it the ideal choice for groups with varying levels of technical expertise. Integrated Character Sheets Roll20 features thousands of community and official character sheets that handle the math for you. Clicking an attribute or a weapon on your sheet automatically sends the roll to the chat window, applying modifiers and calculating critical hits instantly. The Roll20 Marketplace The platform boasts the largest digital storefront in the industry. You can buy modules for D&D, Pathfinder, Call of Cthulhu, and more, which come pre loaded with maps, tokens, and journals, drastically reducing a Game Master's preparation time. Dynamic Lighting and Layering Subscribers gain access to a powerful lighting system that restricts what players can see based on their character's line of sight. The Game Master can easily manage different layers for maps, tokens, and hidden notes that only they can see. Built in Video and Voice Roll20 includes its own integrated WebRTC video and voice chat system, allowing groups to see and hear each other without needing to run third party software like Discord alongside their game window. Jumpgate Technology Introduced in 2024 and 2025, the "Jumpgate" update overhauled the core engine to provide a much smoother, high performance experience. It improved frame rates, reduced loading times, and modernized the interface to compete with newer, hardware accelerated platforms.

Fantasy Grounds Unity is a high-power virtual tabletop originally released in 2004 and completely rebuilt on the Unity engine in 2020. Developed by SmiteWorks, it is the industry pioneer of "automated play," where the software handles complex rules, modifiers, and combat math natively. In a massive industry shift in late 2025, the platform moved to a completely free-to-play model, removing the traditional $50 license fee to compete directly with modern browser-based rivals. Description Fantasy Grounds is often described as a "Digital Dungeon Master’s Assistant." It is a standalone application (not a browser site) that provides the most stable and deep automation available. While it has a more traditional, window-based interface that can feel daunting to new users, it rewards the "Power GM" with unparalleled control over combat and data. Since becoming free in late 2025, it has positioned itself as the premier "zero-cost" entry point for groups who want professional-grade automation without a subscription. System Overview & Key Features Native Ruleset Automation Unlike other VTTs that rely on community plug-ins, Fantasy Grounds features "Hard-Coded" automation for its primary systems. When a player drags an attack onto a target, the software automatically checks for cover, calculates the hit against Armor Class, applies damage, and tracks temporary hit points or resistances without any manual input. V5.1 Visual Intelligence The 2026 update introduced "Aggregated Notifications." Instead of scrolling through a wall of text in a chat box, combat results like damage, saving throws, and status effects now appear as elegant visual icons and pop-ups directly over the tokens on the map. 2.5D Tactical Mapping While it supports traditional 2D top-down maps, FGU includes a unique 2.5D camera mode. This provides a sense of depth and perspective to battlemaps, making the digital table feel more like a physical diorama with "placeable" 3D-like objects like trees and furniture. Total Offline Capability Because it is a localized application, you can prepare your entire campaign, build NPCs, and write story entries without an internet connection. Your data is stored on your hard drive, giving you total ownership of your campaign files. The Fantasy Grounds Forge FGU features an integrated marketplace and community portal called "The Forge." This allows GMs to browse and auto-install thousands of community-made extensions and themes that update automatically whenever the main software is launched. Cross-Platform Unity Engine Built on the Unity 6 engine (as of 2026), the software offers smooth performance on Windows, macOS, and Linux. It uses hardware acceleration to handle complex dynamic lighting, weather effects, and large-scale vision blocking for massive dungeon crawls.

GURPS (Generic Universal RolePlaying System) is a tabletop role-playing game designed by Steve Jackson and published by Steve Jackson Games. Initially released in 1986, with its current Fourth Edition published in 2004, it provides a universal ruleset built to accommodate any conceivable genre, setting, or power level. The system is recognized for its high degree of modularity and its strict reliance on point-based character creation rather than traditional classes or experience levels. Description In GURPS, players construct characters by allocating a predetermined pool of Character Points. These points are spent to acquire core attributes, specific skills, and advantages. Players can also elect to take disadvantages, such as physical limitations, phobias, or social stigmas, to gain additional points during the creation process. The game functions primarily as a mechanical toolkit rather than a fixed set of rules. Game Masters are instructed to select only the specific mechanics, combat modules, and magic systems from the core rulebooks and supplemental materials that fit the intended tone and setting of their campaign. System Overview & Key Features 3d6 Task Resolution The system exclusively uses a pool of three six-sided dice (3d6) for action resolution. To succeed at a task, a player must roll a total equal to or lower than their character's modified skill or attribute target number. The use of three dice generates a bell curve probability distribution, which makes average outcomes statistically common and extreme successes or failures mathematically rare. Point-Buy Character Creation Character generation is entirely point-based. The Game Master assigns a starting total of Character Points (CP) to dictate the overall power level of the campaign. Every element of a character, including the four basic attributes (Strength, Dexterity, Intelligence, Health), specialized skills, wealth, and social status, is purchased using these points. Universal Modularity GURPS is structurally designed for adaptation. The core rulebooks provide the foundational mechanics, while hundreds of supplemental books offer optional, granular rules for specific settings, such as cybernetics, realistic martial arts, space travel, or varied magic systems. The ruleset is intended to be heavily customized and scaled in complexity by the Game Master. Tactical Combat and Damage Resistance Combat encounters operate on one-second turns, creating a highly detailed and tactical framework. The system incorporates rules for hit locations, weapon reach, bleeding, and shock penalties. In combat, armor functions as Damage Resistance (DR); it directly subtracts from the numerical damage inflicted by an attack rather than making the target more difficult to hit. Skill Defaults When a character attempts an action for which they do not possess the specific trained skill, the system utilizes a "default" mechanic. The player may roll against a closely related skill or a foundational attribute, applying a predetermined numerical penalty. This mechanic simulates a character attempting an unfamiliar task using their general knowledge or raw physical capabilities.

Index Card RPG (ICRPG) is a universal, fast-paced tabletop role-playing game designed by Brandish Gilhelm (Hankrin Kapuf) and published by Runehammer Games. Originally released in 2017, with its definitive "Master Edition" published in 2021, the system is designed to strip away the mechanical bloat and analysis paralysis often found in traditional d20-based systems. It serves as both a standalone game and a philosophical design toolkit meant to be hacked, modified, and integrated into other role-playing systems. Description ICRPG is highly customizable and natively includes multiple distinct settings within its core rulebook, ranging from traditional high fantasy (Alfheim) and gritty sci-fi (Warp Shell) to weird west prehistoric survival (Ghost Mountain). The system treats game mastering as a visible, high-momentum performance. Rather than hiding information behind GM screens, ICRPG brings structural elements, like turn timers, room difficulties, and tracking metrics directly into the open. The game derives its name from the use of standard index cards to abstractly map encounters, represent terrain, track turn order, and quickly visualize items or monsters, eliminating the need for complex grid maps or expensive miniatures. System Overview & Key Features The Room Target Instead of assigning different Difficulty Classes (DCs) or Armor Classes (ACs) to every individual object, monster, and trap in an area, the Game Master sets a single "Room Target" number for the entire scene (typically ranging from 10 to 15). Every single d20 roll made by a player in that room, whether it is an attack roll, a saving throw, a stealth check, or an arcane spellcast: must meet or exceed that exact same Target number to succeed. The GM can temporarily adjust this target up or down by 3 points for specific tasks that are explicitly "Easy" or "Hard." Loot-Based Progression Characters do not possess traditional levels, nor do they gain intrinsic stat increases or health boosts when accumulating experience points. Instead, character progression is entirely physical and external, driven by "Loot." Every class feature, stat modification, magical spell, and unique ability is physically tied to an item equipped on the character sheet. If a character's gear is destroyed, stolen, or voluntarily traded to an ally, their mechanical capabilities shift completely, forcing players to focus on acquiring and managing an inventory limited to 10 carried and 10 equipped items. Visible Turn Timers To prevent tactical stalling and maintain pacing, the system relies heavily on explicit, visible timers. At the start of an encounter, the Game Master openly rolls a four-sided die (1d4) in front of the players. This represents the number of rounds remaining until a cataclysmic or complicating event occurs, such as a cave-in, the arrival of enemy reinforcements, or a bomb detonating. This mechanic converts passive exploration into an immediate, high-stakes tactical countdown. Abstract Range Zones Tactical movement completely abandons feet, meters, and grid counting in favor of four abstract distance zones: Close (touching or within arm's reach), Near (a few steps away, reachable within a single move action), Far (within sight and shootable, requiring a full dash to reach), and All the Way (distant or requiring specialized long-range capabilities). Positioning is easily tracked using index cards as relative zone containers. Links runehammer.online - Official homepage for Runehammer Games

The Medieval Fantasy City Generator (MFCG) is a highly influential, browser based procedural tool created by the developer watabou. Since its debut in 2017, it has become the gold standard for "instant" urban cartography, capable of generating complex, aesthetic city layouts in a single click. In late 2025 and early 2026, the tool received significant updates to its District View and Building Placement algorithms, allowing for more organic street flow and higher density urban "slums" that better reflect historical medieval layouts. Description The Medieval Fantasy City Generator is a "toy" in the best sense of the word—a lightweight, highly customizable application that prioritizes "cool looking" maps over strict geographical simulation. It uses Voronoi diagrams to partition space into districts, then fills them with procedurally generated buildings, walls, and landmarks. Because it runs entirely in HTML5, it requires no installation and is a favorite for GMs who need to generate a "capital city" or "coastal port" on the fly during a live session. System Overview & Key Features One Click Generation Pressing a single key (Enter) generates a completely new city with unique geography. The tool automatically decides where the castle, the temple, and the market square go, providing an instant foundation for a Game Master to build their narrative upon. Procedural District Mapping The 2026 version features an improved "Alleys and Blocks" view. Cities are divided into logical districts—like the Craftsmans Quarter or the Shanty Town—each with its own architectural density and procedurally generated name that can be edited by the user. Dynamic Warp Tool GMs can manually reshape the city by "warping" its boundaries. If you need a city that is long and thin to fit a specific riverbank, or a circular fortress atop a hill, the warp tool allows you to push and pull the city's footprint while the buildings rearrange themselves in real time. 3D City Viewer Integration By exporting a city as a JSON file, users can open their map in the companion City Viewer app. This transforms the 2D layout into a fully navigable 3D environment, perfect for showing players the "skyline" of the city they are about to enter. SVG and JSON Export Maps can be exported as high quality SVG files, allowing them to be opened in programs like Illustrator or Inkscape for further artistic customization. The JSON export ensures full compatibility with other "Procgen Arcana" tools and major VTTs like Foundry. Azgaar's Integration The generator is natively linked to Azgaar's Fantasy Map Generator. When a user clicks on a city in a world map, it can automatically trigger the Medieval Fantasy City Generator to build that specific town, creating a seamless "World to Street" experience.
