Computer Games with kids

Kayley
Hi, just wondered how many of you (mainly families) have a game console linked to your living room TV?
My husband has the Xbox One in the living room, and his 2 boys (who share a bedroom) have an Xbox 360 in their room.
We have the boys every other weekend and the eldest (10 years) disappears to his bedroom and we only see him at meal times. 
The youngest (6) has now started playing on the Xbox One continuously from 10am - taking up the living room tv.
Currently, at 9:15am my husband is on the Xbox One, playing COD with 6 year old watching. I asked him to play with his toys but he wants to sit watching - asking questions about the game.
This is seriously annoying me because I can see this is going to become the 'routine' !!
Does anyone else have these computer issues and how do/have you stopped them taking over your life - bear in mind, I have a stubborn husband who doesn't see a problem with playing on computers 24/7...
