Want the fast flowing action of Dungeon World, but want to apply it instead to something like Dresden or Shadowrun? That's why I picked this up.
Hackers. Shotguns. Dragons. What else do you need?
The rule modifications over DW are great, also. Abstract wealth, single roll for attack and damage, car chases. Those are just the low-level tactical bits, the real place that shines is in the setting / genre management tools like "Threads" and the modifications to "GM Moves" and "Principles" are what set the tone on a larger scale.
The layout and art is amazing, also. Really easy to read, well indexed, clean layout for mobile or tablet readers. I'm loving it.
