WW1 is intriguing enough and to think what it must have been like for pilots in those days, true heroes. I have just started searching for resources for the game and the wacky side appeals to me, a snoopy card, a pterodactyl card and the chance to battle King Kong, this changes everything and anything is possible from here. I recently decided to add my own version of mini expansions as well. I did a bit of looking around for the first expansion and found an old news artical "Red Barron shoots down UFO" sooo...it consist of 2 ufo cards their movement is 2 times any card in any movement deck and their attack is 4 damage at 1/2 the ruler and 2 at over half ruler using the A deck. The UFO has 20 damage points and I call the game Encounter. For the second game I add a bit of a Hitchcock feel to the game by adding 2 murder of crow cards and one movement card. The crow cards are multi direction and the direction is random based on a dice roll (d6) 1 six sided die, there is only 1 long movement card. The crow cause 2 damage at 1/2 ruler length only using the A deck and can not be attacked. I call the expansion A Murder of Crow. Im currently working on another expansion called Cereal Flyers which will incorporate Barron Von Redberry and Sir Grapefellow (cereal box characters). So if anyone knows of other interesting items like these please share........enjoy
