All the nerd hobbies are at the bottom of the list scoring negatives. Linux, video games, Warhammer, D&D and other, etc. this is why despite playing a music instrument, I couldn't get laid.
Eh, I find a lot of people the attraction is towards the person themselves and that makes them more interested in their hobbies anyway. Like if someone is into you, they'll probably try to take an interest in Warhammer or whatever because you're into it.
