"Edit: it's not a strawperson. People are biological systems. Spending 3 hours a day with something makes one better or worse, stronger or weaker, faster or slower, never the same. It's sort of like a business: if you're not making money, you're losing it."

I'm not going to say "violent games good, you stupid. Me win argument." I'm going to say they can be good or bad depending on circumstances, just like any media.
