Teens, Games and Civics

"Teens, Games and Civics" was a fact laden presentation about teens and gaming. Three things I learned from this presentation were:

• 31% of the teens surveyed were daily gamers. Considering they included several platforms including cellphones, I thought this number would be higher.
• Top 5 Game Genres for Girls: Puzzle, Racing, Rhythm, Adventure, Sports/Strategy
  Top 5 Game Genres for Boys: Action, Sports, Racing, Adventure, FPS                    
• 63% report seeing or hearing "people being mean and overly aggressive while playing". This did not surprise me. Having played many hours of games online, I constantly amazed at the lack of civility in the gaming realm. The anonymity seems to lead people to believe that they can say whatever they want with no consequence.

I was surprised by the statistic "5% of parents of gamers say gaming has some negative influence/some positive influence, but it depends on the game." I figured this number would be higher with a greater percentage saying gaming had a negative influence. Additionally, I found it hard to believe that 90% of parents said they knew what their children were doing in games. I wander how many actually know and how many just think they know.

Question:
Why is there a higher percentage of boys who play games? Are most games geared toward boys?
