One of the key arguments in the fight for an R18+ rating for video games is that each and every next gen console has parental lock settings to make it much harder for your kids to play your copy of Modern Warfare 2. But how many people actually use them?
My little one is still a little small to need the parental locks switched on just yet, but it's definitely something I'll be using once he's developed his Dad's passion for gaming. But do parents actually use the settings? Are you even aware that they exist?
If you do use them, what are your thoughts? Do you find them effective?
