Actually this study doesn't seem to show that games are harmless. The magnitude and variability of the effect for both TV time and games is similar. There are however far fewer children in the study playing games than watching TV. So the coefficient is statistically significant for TV but not for games. It seems it would be more accurate to state that all kinds of screen time have small negative effects on behavior but the effects of video game time should be more carefully studied in a follow up study with more subjects.
