it isnt acceptable at all. I didnt get my first shooter till I was 12. doesnt mean I hadnt played em, but it just isnt appropriate.
ESPECIALLY HALO 2
if they were a few years older, then by all means, the first halo would be fine. BUT halo was originally created with the T rating in mind. Halo 2 was created with the M rating in mind.
T= pg-13
M= rated R
I think you guys are giving six year olds too much credit. They dont even know how to write very well for god sakes.They play hide and go seek, and eat Alphabits.
They are alot of games out there that a perfect for kids. Let them grow up and then they can play more mature games.
And its really funny Phoenix saying that a 6 year old is mature.
If you're willing to take the time to create a thread on a message board to see if it's appropriate enough for your children...
Then I think you should either:
a.) sit down and play it to see if you approve of it as a parent
b.) sit down and play multiplayer with your kids...they'll love the bonding...and you can make sure they don't get all psycho as they grow up.
