I tried many many unsuccessful times to get my GF to play videogames. She is a total freak too, I figured how could she not like video games?
When I first met her she had purple hair, clearly visible skinny puppy tattoos visible through her revealing outfit. Her username on the internet was taken from a Fluke song that was created for a video game; in fact she basically spent all her time cosplaying the mascot for my favorite playstation game, Wipeout. And she loves the band that made the soundtrack for one of all time favorite PC games, Descent II, so much she has their logo tattooed on her body.
How could she not like video games? I don't know, but she didn't like video games in the slightest. She hated them all. Descent "made her dizzy". Wipeout was "too fast". FPS games were nothing but "stupid war games with ugly characters and annoying sounds". She hated videogames so much that she outright said we couldn't be together if I played games. So I had to quit playing video games for a few years.
It wasn't until I got a ps3 to replace her broken DVD player that she changed her mind about the subject. First I got her to play Flower, and she -really- enjoyed it. Then I got her to play Eden with me, since it is co-op. We played it together for hours on end... now we are ranked in the top 25 worldwide in 2 player mode. Then Wipeout HD came out with auto-pilot and motion control features that allowed her to actually enjoy the game. Next I got her Shining Force EXA and it made her cry. She hit level cap (198) in just under 2 weeks.
Then I got her a copy of Aion and showed her how much better PC gaming was then consoles. Now she is widely regarded as one of the best clerics on our server and her services are often requested by the most hardcore raiding guilds in vent. She is still very picky about games, she tends to dislike games that are overly aggressive, not aesthetically pleasing, or are 'too manly'.
