Another game at the Con was a massive Wings of War (over 40 players). To run such a large game, the people running it simplified it. See my card below for the Camel I was running.
I learned one thing from all of this. If I am ever outnumbered, I'll fly right into the furball. It is safest there (at least it is if you are up against five or six planes being flown by different players).
