Video Game addiction is a real thing, my friend just did his master's thesis on it. My husband likes to play online role-playing games, right now it's Star Wars Online. But he has scheduled nights to play and only plays on the weekends if we tell him it's ok. He knows that I refuse to be second to a game, I had a bf who I could literally walk naked in front of but if he was playing Final Fantasy, it was more important, and that's one of my deal breakers. Plus he understands that family is more important than gaming.
But it can be an addiction, so if she's really worried, she needs to talk to him about it.
