With a few weeks to go the Lost Lands: Bard's Gate Kickstarter is the latest mega-manual to come out of the Frog God Lair. Check it out:
I'm in for the $100 level for a 5E edition. I waffled on The Lost Lands: Borderland Provinces Kickstarter and regret it (when I finally landed my book copies through retail I was incredibly impressed). The Kickstarter is covering 5E, S&W and Pathfinder editions, this time cleaning up the process by letting you elect your preferred edition in the backerkit section. I've cancelled other KS's to make room for it, in fact.
I'm sincerely hoping 5E dominates as a request; I'd love to see older Lost Lands tomes converted to 5E (though converting the S&W versions is easy enough). In fact I'd really love to see Razor Coast converted to 5E although based on the history of that particular production I'll assume such a conversion is likely a pipe dream for now!
