Oh yes, she would. Honestly, the only problem I've found with a gamer spouse (and trust me this is a good problem to have!) is that there is almost no such thing as "single player" anymore =P
If I want to play a long single-player campaign on my own schedule (rarely happens these days anyway!) I'd have to sit her down and say: "look, this game is too time-consuming to play between our separate schedules ... you play one of your games while I'm doing this one" and then she gets a little sad, but then she is happy once she goes back to Puzzle Quest for eight-hundred-billionth time ^_^
Just watch out. My wife gamed some when we were dating but, once we got married it went out the window.
To me the exact opposite happened. My wife in attempting to enjoy my hobbies with me has picked up golf and played several games with me including Kirby's Epic Yarn, Mario All Stars, Flower, Heavy Rain, and Portal 2. She has even played my 3DS more than I have ever since we got Nintendogs + Cats: Toy Poodle or whatever.
As a tradeoff, i agree to go out and about shopping with her on occasion and watch classic movies/tv shows with her. Marriage is all about compromise if you're with the right one.
