Major discount department store franchises Kmart and Wal-Mart announced today on Capitol Hill that they will begin to enforce the Entertainment Software Review Board ratings by refusing to sell games that bear the "Mature" rating to individuals under the age of 17 and not accompanied by a parent or legal guardian.
As reported by the Associated Press, a barcode scanner will be used on game boxes to alert clerks to check for ID for the purchase of M rated games.
Kmart and Wal-Mart are not the first companies to enforce the ESRB ratings, however. Toys "R" Us currently upholds ESRB ratings and does not sell games with the Mature label to minors. Other stores refuse to sell M rated games entirely, which is the course of action endorsed by lawmakers such as Alabama Senator Jeff Sessions and presidential candidate Al Gore's running mate, Senator Joseph Lieberman.
