My first wife hated video games and hated my playing them. It didn't matter if I was playing them even while she was at work, she hated anything and everything to do with World of Warcraft. She also hated D&D. About a year ago when my kids were visiting I took my son with me to a game and got him into D&D as well and she got super pissed off about it. I told her I didn't care, he loved it and as long as he did I would encourage him to play if he wanted.
Anyways, back to the first marriage...I didn't even play WoW much, I raided only after she was in bed but it didn't matter. I never understood it.
When I play games now I can go all day with her doing her own thing and me doing my own thing but as soon as I load a game up she senses it and wants me to do something, so I usually just play after she's in bed as well, which she's fine with. I still play D&D twice a month, which she sometimes doesn't like (most the time) but it's mainly because shes so introverted that she wants me to be too and she gets upset at times that I'm not. (which sounds weird to me, but whatever.)
So I still game quite a bit, just the hours altered to fit the life I have now.
Here's a question though, which I found weird when a friend was telling me about it. Does your wife expect you to go to bed at the same time she does? Mine thankfully doesn't but I have a friend who can be in the middle of something and his wife will be like "well, I'm going to bed" and she will expect him to do the same. Doesn't matter when it is, what he was doing and it doesn't even have anything to do with sex...he just has to go to bed too. That shit blew my mind.
