Right, well done Wang.
Now lets try the same experiment on:
1. People watching violent movies
2. Troops in a war zone
3. Aggressive sports - rugby perhaps?
I'd say it's pretty damn obvious it's going to effect your brainwave patterns, however, it's a case of what other activities do the same?
It's also a case of a *tiny* sample group - I mean, 22 people? WTF?
And how long after did they keep reading the brainwave patterns?
It's just not ... science.
No matter which way you look at this, it smacks of "we want to find the results we expected and they better indicate that violent games make you ... violent"
So, then there's me, I've played a fairly massive amount of video games in my time, to the point where, at 44, I'm bored of most of them (except anything Valve or Rockstar create)
I started gaming age 11, 33 years ago.
And hell, I'm the most passive, non-violent, agreeable chap you could hope to meet, aside from that sticky incident with the crowbar, never put a foot wrong. But hey, we all make mistakes... details, details!
