MMOs and other online games have such a wide appeal that they attract players of all ages. Some MMOs simply add a minimum age requirement to the signup process and advise parents not to let their children play, but others implement strict parental controls. Blizzard recently released a new video explaining the parental controls that parents can use to monitor and control their childrens' play time in World of Warcraft, Diablo III and StarCraft II.\nParents can use the system to limit the total number of hours an account can play each day or week or even schedule specific play times on a calendar. The controls can also limit the use of RealID and voice chat and even mute all of the game's chat channels if necessary. Parents can also disable Diablo III's real money auction house and use of the Blizzard forums. WoW Insider suggests that parental controls may actually be equally useful to students who need to limit their play time or any player who might want a weekly report of his activity. Read on to see the full video and find out how to use parental controls on your child's Battle.net account.
