If she doesn't play Starcraft, Diablo 2, Diablo 3, Halo, or Left 4 Dead 2, there's no way I could be in love with her. Finding a woman that's actually attractive and plays any of these is impossible and typically a red flag, so...
I actually believe that if your bf/gf shares your hobbies, it would be very boring. if I ever found someone (a huge if), I would prefer that he is not into the same things I am into, such as astrology. having different interests and then asking them about it is how you grow.
