This wiki is an attempt to create a comprehensive and concise overview and analysis of the many roleplaying systems out there.

System versus Setting
Many systems are tied to one specific setting. If the system has no separate name from a setting then it is ok to list it with that name, but do remember that it is the rules and not the setting that should be described. It would be correct to mention that the rules are created for a specific setting and when the rules are very integrated with a setting, it is appropriate to have some information about the setting to explain why the rules were designed the way they are. There is already a place for campaign settings in the [http://arcana.wikidot.com/campaign-setting]. Provide links to setting descriptions under the "Links" header of the relevant system.
One System - Many Names
If a system has several names and editions, as well as commonly used abbreviations, try to group them all under its most official name and mention other names, editions and abbreviations in the descriptions. If two editions are very different they may warrant separate entries, but most of the time the latest edition is enough.
Uses
The list can be great for finding the right system for your setting, whether you're a GM, designer or player. Designers are welcome to add their own systems, whether commercial, free, hobby projects or works in progress. Every system also has a section with links to House Rules, where you can create a page with your alterations and extensions to the rules.
Editing
The table uses four columns and systems are listed in alphabetical order. Before you start listing new systems or edit existing ones, read this first and use this template.
