If you want to examine actual angsty social control, just have a look at the work of Oliver Zahm, Ray Chandler, or other photographers crafting a nihilistic vision of fashionable hell on Earth.

The first 'video game' you reveal here is telling: a simulation crafted by the USG itself. You'll note that there are broken people and horror across all the battlefields of the Earth. If you think video games lead that cohort, rather than react to it, your delusion is noted.

Throughout this video, you'll see that inevitably, real games, however grotesque, feature enemies that must be killed to keep them from killing you. None of the mass murders are focused on battle. The video games aren't models, training, or encouragement for such slaughter. They are reactions to a world full of it.

Correlation is not causation. That doesn't matter to disingenuous propagandists intent on misleading people, or those they have successfully misled.
