Man, this game is tough. Love the print-and-play business card idea—super slick and easy to carry. The positioning mechanic with the hexagon zones and pushing your luck to refly targets makes for cool tactical choices.
That said, the rules are a bit muddy on how attack vectors actually map to incoming enemy draws, and flak needs a clearer definition of what counts as a hit.
As for gameplay? Brutal. With the B-17, you're lucky to survive even a single mission. Between getting chewed up by the fighter waves and taking flak over the target, you'll usually get shot down on your very first run—maybe scraping into a second mission if the dice gods smile on you, but don't count on it.
