Recreational Software Advisory Council
The Recreational Software Advisory Council (RSAC) was a non-profit United States organization that rated video games from 1994 to 1999. Mostly supported by PC software publishers it was an alternative to the Videogame Rating Council (VRC) and Entertainment Software Rating Board (ESRB) systems. Eventually it was supplanted by the ESRB system which continues to be used to this day.

Unlike most content rating systems the RSAC categorized games by content, as opposed to suitability for a certain age with three categories: Violence, Nudity/Sex and Language. These were shown by thermometers on the covers of games which ranged from Level 1 all the way up to Level 4 for the most extreme content. As a result a game might have different levels for different types of content. Games which did not fall under these levels were given an "All" label.

All 

Suitable for all audiences. Harmless violence, no nudity/sex/romance and no profanity.
