For example; here is the last experiments from your link:
For Primary studies: "In 2016, a preregistered study of violent video game effects concluded that violent video games did not influence aggression in players.
[19] The preregistered nature of the study removed the potential for the scholars to "nudge" the results of the study in favor of the hypothesis and suggests that preregistration of future studies may help clarify results in the field."
Meta-analyses: "A 2015 meta-analysis of video game effects suggested that video games, including violent games, had minimal impact on children's behavior including violence, prosocial behavior and mental health.
[74] The journal included a debate section on this meta-analysis including scholars who were both supportive
[75] and critical
[76][77] of this meta-analysis. The original author also responded to these comments, arguing that few coherent methodological critiques had been raised.
[78] In 2016, Kanamori and Doi replicated the original
Angry Birds meta-analysis and concluded that critiques of the original meta were largely unwarranted.
[79]"
fMRI: "Further, other studies have failed to find a link between violent games and diminished brain function. For example, an fMRI study by Regenbogen and colleagues suggested VVGs do not diminish the ability to differentiate between real and virtual violence.
[84] Another study from 2016 using fMRI found no evidence that VVGs led to a desensitization effect in players.
[85] In a recent BBC interview, Dr. Simone Kuhn explained that the brain effects seen in prior fMRI studies likely indicated that players
were simply able to distinguish between reality and fiction and modulate their emotional reaction accordingly, not becoming desensitized."
Studies on the effect on crime: "Other studies have examined data on violent video games and crime trends more closely and have come to the conclusion that the release of very popular violent video games are causally associated with corresponding declines in violent crime in the short term. A 2011 study by the
Center for European Economic Research[101] found that violent video games may be reducing crime. This is possibly because the time spent playing games reduces time spent engaged in more antisocial activities. Other recent studies by Patrick Markey
[102] and Scott Cunningham
[103] have come to similar conclusions."
So most recent studies(which is always the most reliable as more advanced research methods and technology is released)say it doesn't do any damage at all, and if it does it's negligible, and it may even help decrease crime.
