Children running to their nearest GameStop to buy GTA IV should think twice. A recent survey conducted by the Federal Trade Commission revealed that overall, 80% of underage shoppers were denied purchase of M-rated video games.

This is an improvement over a 2006 FTC survey, which indicated that a mere 42% were not allowed to make such purchases. The results are part of a larger nationwide survey on retailers’ vigilance against unaccompanied children purchasing CDs with the Parental Advisory Label, M-rated video games, tickets to R-rated movies, R-rated DVDs, and unrated DVDs that were R-rated in theaters.

In terms of M-rated games, the survey gathered data from eight major retail chains: Toys R Us, Wal-Mart, Hollywood Video, GameStop/EB Games, Kmart, Circuit City, Target, and Best Buy.

The results revealed that GameStop was the most stringent, refusing sales of M-rated titles to minors 96% of the time, followed by Wal-Mart’s 82%. On the other hand, the biggest offender was Hollywood Video, which turned down sales to minors only 60% of the time, followed by Circuit City with 62%.
