that there is a school for magic

Show her the beast mode.

sounds like my gf's experience, even playing portal...

I can just about show her the pretties in Skyrim (Darkwater Crossing Waterfalls).

As someone said, overexposure will kill her interest so limit her until she is ready. Also make the whole experience focused on her and what she is thinking. Dont expect her to be in awe at the bits of skyrim you are, she might find other bits more interesting, or sadly none of it interesting at all. dont force it, if it comes, it comes.

this EC video might help you think of some ideas: http://penny-arcade.com/patv/episode/sharing-our-medium

I'm slowly corrupting my girlfriend with Sims 2 and 3. I bought her Sims Medieval and she played it a tiny bit, but boy does she love regular Sims.

I don't hold a lot of hope that someday she'll progress to a game like Skyrim, but there is a chance.

One thing I do is let her assist with the character design. This is her favorite part of any game. She REALLY loves designing how they look, both facial features and clothing. She does a pretty damn good job of it. She made an almost look alike Heath Ledger in Sims 3.

Show her the Dragons flying backwards and how your toon mage gets totally owned due to no magic protection any more.

I hate you, you lucky son of a [censored].

Lmao... Funny posts people. My gf loves watching me play... I feel victorious in life.
