Absolutely.

Video game violence continues to be a topic of debate, for better and worse. Recent studies continue to show that it's possible that violent video games have some impact on the brain and/or body, although most recent studies also suggest that playing violent video games doesn't have much of an impact on real-world behaviour. As the article says, Bushman is still last-authoring studies about video game violence. Most of the studies with Bushman's name on them suggest links between violent video games and aggression. Quite a few have had errata published about them. That's obviously concerning, although not being a cognitive science person, I have no idea how standard (or non-standard) errata are in that field. FWIW, Bushman isn't the only one whose name comes up in studies that link violent video games to aggression.

Measuring things like "aggression" will always involve some level of subjectivity. How you define "aggression" can have a significant impact on your findings. Is it increased cortisol levels? Where people aim if asked to shoot a gun with rubber bullets? What words people choose if asked to complete a story? Each of these offers an incomplete picture of aggression, at best, and pretty much any good study on this topic suggests that more work needs to be done.
