I know a girl who's heavily into WoW. And D&D. But thats it. I've showed her half-life 2, which she liked for the story and setting, and the fun things you can do in Gmod, and she even played through the beginning of Half Life. But, she couldnt seem to get the hang of the controls (like Strafeing, or crouching), and I dont think she liked the stress of the first level. SHe got to the crashed elevator, fell off, died, realized that the game didnt autosave, and said she didnt want to continue. Didnt seem worth it to go through all that crap again i suppose, which I could understand.
She probably picked up bad habits from WOW, and not just the control scheme. In wow, you have a level of detachment and control, via the third-person view. in any semi-horror action FPS, full of scary things or shocking things, chase sequences, and in general, all the things that a good FPS has, it's YOU that being threatened. the horrible tentacle monster or galloping Hunter is flying right a Your FACE.
I think she plays games to relax, and sees FPS as a stress-inducer. Could this be revelaing of something, or is it just an isolated case?
