Halo 2 is by far the best game I have ever had the pleasure to play. The graphics are incredible, the music is impeccable, and it's just an overall great video game. When ESRB rated this game M, I was outraged. I mean, you're shooting aliens here, and there's little to no blood. (plus, it's whacked colors, like green and pink) The only time there is ANY human blood at all is if you shoot your partner, which even the youngest of children understand is morally wrong, and they'd never do it. (At least, my little ones don't) When the ESRB said it's scary, I just laughed out loud. The aliens are well-done, but I don't really think they're going to make you pee your pants or anything. There is absolutely no gore at all in this, despite what the ESRB says. There is a bit of blood, but like I said, it's mild and discolored. The language is extremely mild; I only heard about 5 d*mns and maybe 1 crap in the whole thing. It could at least of been rated T, but I don't think it even amounts to that. I think this is along the lines of E-10+ more than anything. CSM believes that the message is bad because we're attacking aliens. What the heck are they talking about?! Aliens are invading us, and we're simply defending ourselves! My two sons, Trent and Jacob, simply enjoy this game. I don't blame them, as I'm an epic halo fan myself. So buy the game, share it with your children. (If they're mature for their age) I don't think you'll regret, and neither will they.
