If a girl I just met asked me what I do for fun, I would tell her that I like to play video games.
I'm not ashamed of it whatsoever, but it doesn't mean I always talk about it.
Video games aren't that big of a stretch, a huge majority of men in their 20's play video games, its our generation.
What you didn't tell her is that you're playing it on a hannah montana psp, and are an avid pokemon egg breeder.
