Both a group that has familiarity with GUMSHOE, and one that does not would be acceptable; or, indeed, both. I’d learn different things from each. Either way, if people are interested I’d need them to grab the rules and play the game in August, and get back to me with feedback by the end of August. Hopefully by then I’ll have an editor to go through the text so I can get it to the layout artist and then get it back to be sold. And maybe the print run Kickstarted.
Either way: if you’re interested, feel free to apply via comments here or email me via Backerkit. If you backed the Kickstarter then you should already have the playtest version in your mailbox already; if you did not, well, it comes free with FROZEN DREAMS in certain pre-orders and I’ve reopened the store.
