As indie game developers we have found ourselves  many times in the need of an easy way to inform players about the content and intended audience of our games. The easiest way to do this is with a rating system, and while the use of these systems is not mandatory in most cases, it is a process that can be very expensive, very time consuming or even both.

Free GR™ is an open, free, unofficial and voluntary game's rating system designed by Irreverent Software™. It has  been designed from zero with indie developers in mind and a comprehensive set of guidelines to help them rate their own games and inform this in a clear way to their player base.

A Free GR™ rating contains a numeric rating displaying the intended age group, a small legend explaining if the game has online features or not ( since these online features are always unrated ) and a certain number of icons that represent in a more detailed manner the main reasons behind said rating.

Take the rating above as an example. It tells the player that the game has been considered adequate for players that are 12 years old and above. The swords icon indicates violence, and the two white bars under it indicate that it is moderate. The second icon clearly indicates bad language while the white bar indicates that it is very low and not frequent.

There are 6 different ratings in our system, for six different age groups. Each group, from left to right, gets progressively stronger content in terms of violence, language, controversial topics etc. The final rating labeled as Z+ is for games intended for adults only and is in general applied for games that are overtly sexually explicit, sadistic or controversial, making them not apt for general audiences regardless of their age. At the very least, your rating should display the full numeric rating. Adding the them icons is not mandatory but is heavily encouraged.

There are 8 available icons for the ratings so far, and their meanings are :
