I didn't play them because I was a kid. I think the first mature game I played was Halo 2 local multiplayer when I was 14 at my cousin's. I've had my Xbox 360 for 4 years so I pretty much started playing them when I was 15. Yes, they did make me more aggressive actually. I would actually punch myself and bite my hand and cuss at the people (people being the players) calling them things like "Cheap ass ****er!" when they were really not. I would even be more aggressive to people that came in the room when I was so pissed off. So I really wasn't old enough to play them either. I just think 11 is way too young. You're not even a teenager at that age.
