I backed the Nations & Cannons Kickstarter (historical roleplaying in the American Revolution using 5E rules) yesterday. Just downloaded the already-published stuff I picked up besides the upcoming book - the core rules, the firearms rules, and the Misfire Deck, which is a critical fumble deck for when your gun Misfires (each firearm has a misfire rating between 1 and 3, so you don't want to roll low on your attack)...
Haven't had time to read any of it yet, but I'll check it out this weekend.
From what I've read here on the forum, it looks like it'll be pretty cool.
Ever since I read the first book in D.B. Jackson's Thieftaker series, about a sorcerer working as a thieftaker in just-barely-pre-Revolutionary Boston, I've been intrigued by the concept of mixing magic into the American Revolution.
