These ratings are accompanied by descriptions such as “realistic blood and gore” and “use of drugs.” Video games do have their benefits, though. Not all games involve graphically killing an opponent. A slew of puzzle games that make you think (such as Tetris and Zoop) are still popular with teens. Also, many video games, from Super Mario Brothers to Street Fighter, help develop eye-hand coordination, and because the games come without instructions or blueprints, teens have a great time sharing gaming secrets and strategies. However, when the love of video games becomes too compelling, it’s time to pull the plug, or at least set some limits. If your teen is placing video or computer games above chores, homework, or even social gatherings, it’s time to lay down some clear rules: No video games until homework is finished, or only one hour of video gaming a night. Video games are not something that should be banned, but they shouldn’t dominate everything else in your teen’s life.
