Coming from a female gamer, I love being able to share that kind of stuff with my partner. But that's the key word: share. My first boyfriend would spend hours playing one-player games and ignoring me... on the one day a week I got to see him in person.
Turns out that was also his one day off of work for the week and he wanted some time to himself, which I guess he felt I was taking away by being around. We never talked about it, though, so I can only speculate.
I guess my point is, communication is really important. You wanna know how someone likes to hang out? Ask them.
