I'm aware that the WW1 & WW2 versions of Wings of Glory deploy their Maneuver Cards in different ways but after playing Sails of Glory we have been trying out another variant.
In SoG a player picks two cards and places them on his ship board, plays the first one and then slides the second across before laying down a replacement on the board, so there is always a delay in the enemy seeing his intent.
We have been doing a similar thing in Wings.
We start with three cards as normal. Playing the first card then sliding the other two across the airplane board before laying down a new card in space three.
Players can look at their first two cards at any time but may not change them except where game occurrences force a change.
It may not sound much of an alteration but having tried it out you really need to concentrate on what you are doing and what your opponent might be doing a lot more, as there is a less rapid reaction through the card turn over to get you out of trouble.
We have played a system of using the length of two range markers as long range and the whole length of one as short range for years and this really suits this approach to maneuver cards, as there tends to be more space between planes when players cannot instantly change all their cards.
All card effects for stalls, dives etc are maintained as per the game.
It does tend to make games a little longer but its well worth a try!
