I played for years Blue Max! It's actually that board game which introduced me to WW1 aviation interest, I was 14yo in 1990
I got so much in love with it that, in years I bought 3 boxes from the 3 editions released in Italy.
I really loved it and spent hours with friends. Even with some huge aids, like the chance to see every plane, everywhere. Or not consider potential/kinetic energy, but man... a game is a game. It's meant to be fun, and it was.
