I don't get these threads, for the simple reason no one other than those people around the child knows what that particular child thinks and how s/he acts.
Like i said in the 10 year old thread:
Not meaning to come across as a complete [censored], but surely the best person to know if your daughter should be playing it, is you, no?
Why do you need my opinion or even want it as I don't know the first thing about your child. 10 year old children can vary in maturity. For example, some can be ok with media beyond their years, whilst others are best kept as far away form it as possible. As far as I'm aware, it's only illegal for kids under a certain age to buy such material, not play it or watch it. That responsibility should fall upon the parents, not some random internet users.
Basically, the game has been rated 'M' and as such, the decision should be based around that and not around the fact that, i, myself don't mind seeing some graphic death move or whatever.
