The first game I played on Thursday was this WWI air battle. It was a Check Your 6 mod to the original set of rules. I played the British and had two Sopwith Camels. I didn't shoot anyone down but I also didn't get shot down. My planes got damaged pretty well and I had fly out of the battle with both planes. The Germans took the day.
The rules played very well and I bought the scenario book the GM had written. It also came with all of the airplane charts.
