Blizzard Entertainment, developer of the hugely popular massively multiplayer online game World of Warcraft, has introduced a new system which gives parents control over when their children can play.
To access the system, parents must login to their child's WOW account and set up a parental control password. They can then design a play schedule which determines exactly when the account is accessible.
There are also a number of preset schedules to choose from. These restrict account access to weekends or evenings, for example, or force the player to take a one-hour break at regular intervals and so on.
Players cannot get round the system by switching between characters - once the parental control system is activated, the schedule applies to all characters registered to the account.
The new system is already up and running and can be accessed via the WOW website.
