Hm...i saw a lot of violence movies etc,and my mom let me see scaries movies that was rated for 15 year,when i was 12 for ex and it hasn' t affect me at all.
But i do know when it happend,remember when i was 6 and some of the kids in the playground brutally kicked another kid in a fight when playing power rangers,in fact he could have died,he kicked and hitting for surviving almost-
Very scary when i rethink about it,but then i never feelt scared,because we thought kicks and hit would not kill or really hurt anyone since we saw people in power rangers just getting up after a hit.
Anyway,after that day our teacher really yelled us at and starting threating us with things i cant remember(ofc not with violence though).
And we never did it again.
Im just glad that the kid survived.
I was in the fight,but we where all fighting each other,i got many bruise.
we really liked each other,and just wanted to do some karate stuff.
We really never thought about what horrible things could happend with each other.
So yes i do think people below 8-9 shouldn' t watch violence at all.
But playing halo2?
Shooting aliens? i dont think that will affect him,but fighting games...
Anyway i do think the gov are being over protective with their laws for watching movies or playing games,but after 10 i think its should be up to the parents.
I never got mad or angry or dreamt bad dreams when watching horror movies.
In fact i was like 12 when i saw chucky ^^ gotta thank my big bro for letting me see it when he was taking care of me.
