Cards too small for decrepit me to figure out, but this flashed me back to an old fave... "Ace of Aces." Do you know of that one by chance? You pick your WWI aerial fighter, then make your move, letting your opponent which code he needs to access based on your aerial "move" (barrel roll, tight turn, etc.). He does likewise, and you access your new book page to see what positions the two of you are now in... (Aaack!)



Pretty ancient by today's gaming (25+ years ago), but I'm gonna have to go wiki it now...!
