I did run a one-shot several months ago using the backer-preview rules. The adventure out of the back of the book. (Sadly this was before the art was finalized so I had to guess with handouts and maps, ha). It was a lot of fun, and I'd def be interested in exploring the world more later on. Though I'm not sure I'm cut out for being a GM in the long-term, personally. Sadly, GR has mentioned that they're out of the offices until Jan 2, so it looks like it'll have to be an early 2017 release. (They mentioned they wanted to send it off to the printer in Oct/Nov I think?). If you are, or know, a backer, the current ruleset is very usable, especially if you're already familiar with the AGE system. (I ran it with my Dragon AGE group).
