How do you get your husband to stop playing video games and spend time with his family

My advice is to hide all the consoles so he can't play. Or sell them on eBay or give them away to the kids in the neighborhood.
I would also advise counselling, but I don't know anything about the situation nor am I qualified to give such advice.

Answer from Dan:
I wouldn't just take them away, for that could cause arguments between the two of you. You need to try meeting him halfway, try to play some video games with him, then maybe he'll develop an interest in things you like to do.
