To make it clear what is included in each of these products is and what is needed to play, I made a video to explain:
Something I didn't go into in the video is what the differences are between 1st and 2nd edition. Luke Crane outlined these on the Burning Wheel Forum for the Mouse Guard RPG:
"We've been gently tweaking rules and reediting the book, both in the text and art. It's been my pleasure to have David involved at every step of the process. [He]...sat with me as we recreated all of the patrols using the revised recruitment rules. It's been great to work so closely with him.
I tried to keep the changes to Mouse Guard is minimal as possible. I like Mouse Guard. It's light and open, while providing enough structure that the game moves along without too much effort. The main areas that changed:
Conflict: Thor & I simplified the individual team and multiple team rules. It's all very straight-forward now.
Wises: We gutted wises and ported over the systems from Torchbearer. This necessitated some minor changes to the Traits rules, too.
Recruitment: I rejiggered Recruitment to make it faster and to make the characters slightly more skilled to start, with a solid base of skills."
Cards: Weapon, Action, and Condition cards and their rules/clarity in the Boxed Set were also updated and significantly improved.
