    What is the CoCGMS?

    The CoCGMS or Call of Cthulhu Game Management System is an app developed on the FileMaker platform.  Thousands of businesses and developers create amazing systems using FileMaker.

    The CoCGMS is a game management system intended to give Call of Cthulhu gamers a complete set of tools needed to create both characters and scenarios as well as provide a wide range of other features like catalog tracking, combat utilities, table creation, dice rolling abilities, and much more.

    Scroll through the showcase here to see some of the system features.

     

     

  • Character Creation

    Character Creation

    The CoCGMS features a great character generation system allowing you to create templates from which you can quickly roll out dozens of randomized NPCs, Monsters or Player character records; each one having a unique blend of stats, skills weapons and equipment you set the ranges for.  The system is highly customizable to give you the ability make nearly any option just what you want.

    Each character record can have any number of character images assigned to it and built in dice rolling tools let you use a character record interactively to speed up the pace of running a CoC game.

  • Scenario Creation

    Scenario Creation

    Many gaming applications focus only on character creation and dice rolling utilities.  But, there's more to a game than just characters and rolling dice.  There has to be something for the characters to actually do!

    The CoCGMS has a powerful scenario development side which will help you create the other half of a role playing game.  You can store any number of scenarios in the system and have all of your content in one place, ready to reference instantly.

    Write your scenarios just like you would a book with chapters breaks to separate things into chunks.

  • Scenario Tools

    Scenario Tools

    Scenarios can be packed with a huge amount of data such as the actual narrative content of each part, images, character links, dialog, combat groups for rapid fighting resolution and even sound boards.

    Load your scenarios up with sound bytes to play for your players to spice up the flavor of a game or even pre-record dialog spoken by an NPC they might encounter at some point to make sure you get the tone just right.

  • Scenario Parts

    Scenario Parts

    In the CoCGMS, scenarios are built by creating parts of the whole.  This allows the keeper to compartmentalize his or her content into easily found and referenced chunks of information.  Major parts of the scenario are broken down into chapters and within those chapters are parts like events, group references, historical information, etc.  These part types are customizable by the keeper to be just what he or she needs them to be.

    Order your parts in the logical order you need and move sections easily if necessary.  Attach images, notes, dialog, printable items and more to each part.

  • Catalogs Galore

    Catalogs Galore

    Use the CoCGMS to store customized catalogs of anything you may need to reference or assign to characters.  Each package in the system can be loaded with catalogs of melee items, range items, spells, skills, print templates and much more.  Organize things by era or any other logic you see fit to use.

    Nearly all entries can store an image helping you flesh out the feel of all items.  Attach catalogs to packages, scenarios and/or directly to characters themselves to provide a base selection of available items.

  • Table Concatenation

    Table Concatenation

    Give your brain a break!  Let the CoCGMS create unique things for your game but concatenating up to 7 tables of things into truly interesting outcomes.  Leverage features that let you build just the right thing generator.  Build interesting names out of syllable strings, generate new insanities, describe people your PCs meet on the street at the click of a button, and more.

    It's amazing what you can come up with by letting the system string together a few random possibilities.

  • The Players Window

    The Players Window

    The CoCGMS is both a behind the scenes development tool set AND an interactive gaming utility designed to be used as you game.  One of the best interactive features is the Players Window which displays things for the players to see as you game like images, dice roll results, table selections, GM jotted text and more.

    Using a third party utility like "Actual Multiple Monitors" you can mirror the contents of the Players Window to a dedicated monitor facing your players.  Turn off the mirroring of content when you need to or clear the Players Window at will to keep the players from seeing too much!

  • Print It!

    Print It!

    Print characters the way you need to.  Print full character sheets for the players, 3x5 quick reference cards for NPCs, tack sheets of just names and occupations to give to players as help sheets for knowing each other or NPCs, tent cards to stand up in front of players, and more.

    Print out your scenarios to have a paper copy handy or print Print Items attached to scenario parts such as journal entries, found telegrams, doctor's prescription orders, etc.  Install a free PDF print driver like PrimoPDF and send everything to PDFs to keep on your computer outside of the system.

CoCGMS Mac Download

The Mac version of the CoCGMS is a runtime build of the software using FileMaker Pro Advanced version 18.  FileMaker offers a feature that lets developers wrap a FileMaker database within a dedicated runtime framework that can only run the database it was compiled to support.  This is perfect for databases like the CoCGMS allowing it to break out of the lab and into the world.

To use the Mac version of the system, simply download the below archive and unzip to a folder of your choosing.  Run CoCGMSv2.app and that's it.  No installation.  Just unzip and run.  You can keep multiple copies of the application in different folders but the CoCGMS is designed to hold separate content in dedicated packages so you normally just need one installation.

The CoCGMS v2.9.0 requires macOS High Sierra 10.13 or better.

PLEASE NOTE: Beginning with macOS Mojave 10.14 and higher, Apple implemented an app signing requirement that the CoCGMS does not adhere to.  Because of this, running the app for the first time may result in a crash that is easily remedied.  To unsign the CocGMSv2.app executable, run this command from a terminal window (replacing the app path with the path you have your copy of the CoCGMSv2.app file in):

codesign --remove-signature /Users/YourUserID/Desktop/CoCGMS-Path/CoCGMSv2.app

You can also enter "codesign --remove-signature " at the terminal prompt and then drag the CoCGMSv2.app file into the terminal window to drop the app path onto the command line for easy reference.

That will remove the signature on the app and your Mac will happily run the program as intended.
