New Delhi, Dec 03 (AN) : A new study has found that playing violent 3D games can increase the anger level in video game players. Those who play violently may show higher levels of anger than nonviolent players no matter how they played 2-D or 3-D. But those who play violently on 3-D are significantly angrier than those who play violently on the 2-D systems.People who play in 3-D are more immersed in the game than the ones who play in 2-D, and that immersion can be related to the increased anger felt by those who played violently.
