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 do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
