Although I'm generally opposed to the concept of game ratings, from a business perspective I believe they may provide some "added value" for consumers in the form of an informational tool. The retail industry has the ESRB and PEGI, but the costs involved are too high for independent developers and the bureaurcacy is too constraining. I think the indie community might benefit from a free-as-in-air rating system which they could use to inform consumers about their games' intended audience. I have created some samples for you to review and criticise. Once the design is complete I hope to create a website to promote the use of the symbols and to provide a set of guidelines for indies to follow. The logos would be released as public-domain images such that following the guidelines would be strictly voluntary, but I expect that given the indie community's involvement the rating criteria could become a de-facto standard. The ratings samples incorporate several elements: a rating descriptor (on top), a color code (in the middle), and a set of recommended ages (at the bottom). The rating descriptor and color code are chosen according to elements of game content (as advice for parents), while the set of recommended ages is chosen according to the game's intended audience (like you see on board games). You may review these elements in the samples I've posted. I'd like to hear your opinions on the rating system and would appreciate your help in developing some rating guidelines for developers to follow.
