So first things first, I love Fisty McCuffs and anything ever happens to them I will rain ENDLESS INDIGNITIES UPON THIS WRETCHED-
Anyway, BBRT's a really clever toolkit. It's a very useful and well-laid out series of tips and tables, with a cute sense of humor that doesn't get distracting. It's welcoming, flexible, and friendly in how it explains what FIST is, the type of games you can run with it, and how to navigate those little moment of indecision likely to arise no matter HOW long you've been GM-ing.
I can sort of see the seams on where this was a bit of a later entry and maybe design wise there could have been a further push on the early GUI interface vibes, but overall the actual content of the toolkit is what matters and the simpler look overall makes it easier to print without losing that vibe.
Just a really great tool kit I plan to use immediately!
