The 3DO Rating System was a rating system created by The 3DO Company and used on games released for the 3DO Interactive Multiplayer. The rating system has four categories:
- E - Everyone
- 12 - Guidance for 12 & under
- 17 - Guidance for 17 & under
- AO - Adults Only
These ratings would appear on the lower front and back of the packaging, while the back of the packaging also specified what content was present in the game. This rating system was discontinued after the Entertainment Software Rating Board was established in 1994 and from then on, 3DO games were rated by ESRB.
