Many children and teenagers spend large amounts of time playing game．Most of the games have become very complicated and realistic．And while some of them have educational content and promote learning，problem solving and help with the development of motor skills，others emphasize negative themes and promote killing，fighting，criminal behavior and violence in general．
There is growing research on the effects of video games on children．Numerous studies show that video games，especially ones with violent content，make teens more aggressive．Children exposed to violence can become addicted to the horror of violence by imitating they violence they see，and showing more aggressive behavior themselves．Some children accept violence as a way to cope with their own problems．Studies have also shown that the more realistic is the exposure to violence，the more impressed children are．Also，children with emotional，behavioral and learning problems may be more influenced by violent images．Playing video games may increase aggressive behavior because violence is considered an effective teaching method in strengthening learning patterns．
Children and teens who become overly involved with video games，and，therefore，spend large amounts of time playing these games can create problems，such as poor social skills，time absent from home，lower grades at school，less reading less exercising and becoming overweight，aggressive thoughts，behaviors and so on．
Parents are responsible for helping their children in choosing books to read，toys to play with, TV programs and movies to watch，which are appropriate for each particular child．Entertainment materials should be fun，engaging，exciting and educating．Parents should have a good knowledge and understanding of each child so that they can assist them in selecting appropriate learning materials．Parents should invest more of their time playing the games with their children，as well as talking with them about their impressions, thoughts and feelings related to the playing game．They can also engage in a discussion of great values that may．guide the child down a safe road and lead to the development of a moral character．
