IS there anyway to block Overwatch if it's played more than a few hours a day?

I know someone who is addicted to Overwatch and stays up all night playing it. Are there any parental controls or something you can put on his computer to block him from playing more than a couple hours a day?

Disable internet access to his computer if he doesn't stop playing when you tell him to. Assuming this is your child you're talking about.

@vagrantsnow: A friend's child. He doesn't know much about computers. I know that if you have their battlenet login info you can set parental controls, but are there any other kinds of software you could install on his computer that would limit the time the game can run or at the very least maybe show him how much time he's spending playing it?

Some routers - mostly mesh settings got smart parental control which you can set times for devices to be connected to the Internet

@Maxpowers_32: If on Windows 10, it may be built in. Check this out: https://kidlogger.net/blog/parental-control-in-windows-10.html.
