If shes not into games, then don't try and make her. Get out, go for a walk, go see a movie, go to the park, go on a roadtrip every now and then, just get out and do stuff outside the house, and on top of the, outside a TV.
Now if she does like video games, you can't ALWAYS make that your primary form of interaction, chances are it won't work too long. You still have to get out and do things outside the house. If you know how much stamina your girlfriends gear has but not where she grew up, heres a giant facepalm to you!
I am reorganizing the site I know nobody will notice but I am not done quite yet but the main forums order has been changed and there is a new news category in Other News which is all the remaining headline news stuff not categorized - Headline News is just the stuff that shows on the main page now and the news archive is off the main forums page
