After an unfortunate delay, Brent Wolke is back with another awesome 8-page Risus setting. This time, it's a cinematic steampunk world of high adventure in the aftermath of a failed Martian invasion. Check out the engine of thwaak for Brave the Impossible as well as updated versions of his previous work. Each of the settings are handsomely presented and contain cool little nuggets that you can important into all sorts of Risus games. For Brave the Impossible, I particularly like "Society Dice" (a neat little Questing Dice variant).
Incidentally, the timing of this couldn't be more perfect given the long posts that I'm still trying to assemble.
