We've got ESRB, they determined the game is rated T. I don't have problems with this, game is using pew pew guns to shoot aliens, I don't have problem with kids playing any kind of fantasy violence, hell I played resident evil when I was 11, The only thing I do oppose is super young kids playing hyper realistic shooters, like people letting their ten year olds play call of duty. But any game that detaches from reality, don't really care, like you're an undead space wizzard using a laser gun to shoot space zombies on the moon ffs.
