I thing the problem stems from the wife playing the game/s when she should clearly be the 1950's housewife attending to the family needs at the drop of a hat, always on hand ready to be the dependable one springing to action when a drink needs making or the kids need help with homework, etc.
A woman isn't supposed to be 'playing' on the computer, she is there for practical reasons only, and the man is the one that deserves downtime after a hard day at work. For decades it's always been accepted, expected and unquestioned the man gets to 'play' whether on the computer/console on various games, watching the footie, go golfing, paint balling etc.
It's a sad fact a lot of people still have the mindset of the woman not being allowed to have a hobby that isn't in some way 'contributing' or 'traditionally acceptable'. I personally play games on the XBox, it's a great way to unwind, is entertaining and you can still be talking to others either in the room or online. A lot of games require you to view cut scenes to know what to do next, which I find similar to watching a film, but with a lot more interaction, rather than only passively paying attention.
The Sims requires a lot of forethought and forward planning when building, which means you are engaging your brain, crack on and enjoy what you love!. Also ask him if he takes the mick out of his friend, or is it just you he has a problem with?.
it's not just older people who think that either, sadly. I've seen plenty of young geeks, not all male either, who think that once a woman turns 30 she should give up all fannish hobbies and devote herself to knitting, doing her taxes and raising the kids. Sure, there's nothing wrong with knitting but not all of us are into it. In the case of fanfic, there's an element of 'older women having sexual fantasies is disgusting' too. Plenty of men draw repulsive fetish art of female cartoon characters but oddly, they get a pass.
Men also do not, as a whole, like women encroaching on what they consider to be 'their' hobbies, be it football or gaming. As my name suggests, I'm a football fan and some men are quite weird about that, or they just automatically assume I'm a man on online forums. Loads of men still dislike women playing, watching or commenting on football and think it's perfectly acceptable to tell us to go back to the kitchen or send rape threats to people like Alex Scott. I get not everyone wants to watch women's football but some men act like acknowledging its existence is like having a gun pointed at their heads and being FORCED to watch it, and some of us genuinely enjoy the game and aren't just there because we fancy the players (Everton have a handsome squad now but some of the squads we had in the '90s/'00s were fugly), and we don't all support big name teams like Liverpool or Real Madrid. And we do know the offside rule.
I also have a friend who likes a lot of music and bands with large male followings - G-dspeed You Black Emperor, Slint, Sunn O))), black metal, etc. When she and her husband have been to gigs together, people just assume she's along for the ride as opposed to, you know, actually liking the music.
However, I am happy to report that when I've done group raids in Pokemon Go, there have been plenty of women there, including mums with kids. Hell, it was a woman who got me into it, she's got Pokemon tattoos! I also use it as a walking app (you get given eggs and you have to walk a certain distance to hatch them, and if you have a Pokemon as your 'buddy', you can feed it candy by walking it a certain distance, though good luck if it's Mewtwo or Meltan). When the weather calms down a bit I'll probably get out there and hatch some eggs.
