Index Card RPG

Overview

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.

The storyteller Narrative minimalist
Let’s go on an adventure together! I'm looking for a free, cooperative, consent-based, story-focused TTRPG table. I enjoy character-driven games with party relationships, meaningful combat, exploration, mystery, downtime, and earned emotional moments. Ideal balance: about 40% roleplay, 20% combat, 40% exploration. I like sincere games with humor, but not constant bits, edgelord behavior, or main character syndrome. I fit best with players who share spotlight, cooperate, respect boundaries, and care about everyone’s character mattering. Consent and safety are important to me. Heavy themes, PvP, romance/flirting, sexual content, intense character conflict, or major effects on another PC should be discussed first. Lines and veils should be respected. I’m in Hawaiʻi Time / UTC-10. Weekends are best, and I prefer 2–3 hour sessions. I’m open to voice, PBP, or hybrid formats. Not a good fit for bigotry, disruptive rules-lawyering, non-cooperative play, unconsented PvP/romance/sexual content, trauma dumping, or using RPGs as therapy.

Usually behind the screen, always happy to grab a seat and try another system. I bring curiosity, share the spotlight, and work with the GM and fellow players to create the kind of moments you only get around a TTRPG table.

I've been playing for a while, but am really into story games (PbtA, CfB, FitD) these days, but open to just about any TTRPG (mostly Indie, though). I play on the Open Hearth gaming community, and am open to other online games, but am hoping to meet others face to face as well. I'm based in Surrey, but can get up to London reasonably easily. I like embracing Improv, play-to-find-out principles, and prefer games that also do so.

DmsTinyHut is a DM platform that want to help DM's get inspiration for their next session. Its not about taking over your prep its about helping you get inspired. The site has no AI or is not built with AI since I find that very important. Some links and explanations: Encounters (D&D) The encounter generator that generates encounters that make sense so that means I have matched all monsters to each other where it makes sense. Loot (D&D) A loot generator that follows the DMG guidelines and automagically updates the loot given based on the party. Magic shop (D&D) A shop generator that has all items from the new DND 5.5 in there. It has logical pricing and a 1 button way to generate a quick NPC shop keep. Encounters (Daggerheart) A Daggerheart encounter generator that has all the content from also the SRD 2.0 in there and I am currently working on adding the same level of matching there as well. Loot (Daggerheart) A loot generator for Daggerheart also has all the new SRD 2.0 content and follows what is dictated by the source books as balanced as well. All with options to save them with an account.
