Transitioning to Game Design from 13 years of Narrative Design experience?

Last year, I was laid off from my job as a Senior Narrative Designer. It's been brutal, as any of you who work in games know, it's the worst job market of all time.

I recently was having a conversation with a game designer who was adamant that I could never do Game Design because of my Narrative Designer background. I was so perplexed by this, and have talked with some others, and was curious what you all thought.

This isn't a case of someone's first outing, but if you had to do it all over again, what steps would you take now?
