Backers of the Ex3 Kickstarter already have the rules, and thus, several people (like myself) are running Ex3 games already. It's a rather inclusive game, however, that relies a fair bit on STs being permissive to players creating their own artifacts, charms, etc., and as a result, groups tend to be close-knit, rather than public. As a result, recruiting tends to be slim, and very, very selective.
