Part 2, the math of the vsM system.
To make a grittier game, change the starting attributes to one 3, two 2's, and a 1.
Change the target values to 10 + the face cards.
Your highest attribute will have a 56% chance of success to do a Hard thing. In other words, draw at least one Queen with three tries from a deck of cards.
I haven't even attempted to deal with opposed draws. Oof! the Math!
