So do sports.

Let's ban under 18s from playing sports.

When's the next paper coming out that says the reverse. How many damn times do studies keep flopping (their dicks) back and forth at what's right.

yes it could lead to aggression, especially star wars games that leads you to the dark side of the force. :)

These studies are such nonsense. They always test it by defining "aggression" as something like "more likely to crush a can of coke rather than throwing it away" or something ridiculous like that.
When you actually compare it to real life violence, there is no correlation at all. In the time that games have increased in popularity, western society has got less violent. Most notably in the 90s. Violent crime fell massively.
