Nice article and so true.
After being married 9 years it does get a little easier. It is seriously very hard to get to a good place with this. The tough thing is that gaming time isn't "your" time if she can come in and bug you anytime.
Some tips that work for me:
-Build a gaming room (man-cave). This is vital.
-Remind her of how expensive and time consuming real sports are. You need equipment, will be gone for hours playing and of course off to the bar afterwords with friends for some "post-game" analysis. When you compare gaming, it is actually cheaper and of course she knows where you are!
-When all else fails, get a good pair of headphones and crank them up to where you can't hear anything else. Just remove all the frying pans from the house first.
