What you describe is classic parental alienation and it sounds like you have proof of this. You need to file a petition in Family Court to enforce the visitation agreement.
I would strongly suggest that you contact an attorney regarding this matter as these types of claims are complex and difficult to prove.

Your situation is not unique and happens to many parents after divorces, often years after the divorce. These situations present the courts with some of its greatest challenges. Obviously, your wife should not be promoting the child to stay home and play video games. But, often, there are underlying issues in the relationship with the child and the parent seeking visitation. Unfortunately, courts are not well equipped to handle this type of scenario. As a result, before going to court, I suggest you try a few alternatives.
First. try arranging fun weekend activities or trips that might lure your son away from the XBox. A trip to an amusement park, football game, etc. If the choice is staying at home with his video games, in his regular room, over cramming into your place for a weekend just to see you, he will choose his comfortable spot on the couch in front of the tv every time. He is, after all, a teenage boy.
If that does not work, try counselling, with a social worker or psychologist to work on your relationship with your son.
Only if all else fails, and your ex-wife blocks the joint therapy, should you consult a lawyer and go to court.
