First off it's not about the game its about her finally compromising to try and spend more time with you, so if your wife is willing to make that kind of compromise in order to spend time with you, at least do something she might find more entertaining then playing WW2 sim. This is a game, that is your family, you make the choice!
Oh by the way, I didn't hear what she was saying until it was to late, its just a game dude!
