A study over at Iowa State University has found that "some non-violent videogames can teach kids to be more cooperative and helpful to others," reports D'toid.
In other words, some games are good.
With probably the longest title ever given to the study of games, "The Effects of Prosocial Video Games on Prosocial Behaviors: International Evidence From Correlational, Longitudinal, and Experimental Studies" was conducted in three countries and included age groups starting at fifth grade and ending in college.
Pro-social games were played and, according to results, the players were more "pro-social" to others for four months afterwards.
The report did say, however, that violent games could lead people to behave more aggressively.
