Don't believe these picture of gamer girls. No one that beautiful plays these types of games. XD
Not that uncommon at all. Always kind of blows my mind that some stereotypes still prevail. For me, gaming was a great bonding tool between my Dad and I. And I just grew up a tomboy naturally attracted to things that are traditionally male-oriented... fishing, (American) football, shooting pool/billiards, beer, bowling, whiskey, video games, etc. I view video games more as entertainment than a nerdy/guy thing... no different than my enjoying books or movies.
And since some are offering up additional photos, here's a few more recent (none in my N7 gear though... will try to maybe get one of me sporting my Lady Sentinel T-shirt once that arrives)...
I'm on the left on my wedding day, that's my (late) mother on the right (passed in January this year):

The Lady Turian Sentinel takes a break from shooting pool to kiss her Krogan Soldier (JLowe, for anyone here who may have played with him):

And my best friend's wedding (the three pictured are the bridesmaids; I'm far left) this past December. Speaking of stereotypes, I am the gamer chick because I am the pasty white one with no tan. LOL

(No, seriously, the Irish genes are too strong in me... I don't tan, just burn):
