One of the easiest and most fun games I've learned to play and run!
I use it for everything: zombie breakout? running a hesit? surviving an absolute end-of-the-world event? Magical girls saving the world once again? This game is what you should be playing.
I especially enjoy what the "stress" and "risk" elements bring into the game. I've seen my players go from confident and smug to losing their shit in one dice roll.
