All I want is an easier way to keep track of what you already know.
It would not be changing the strategy at all - it would just help the players who do not have the time to study the board, keep going through past moves to see what has already happened, etc...
Also the suggestion of knowing which pieces you captured is also a good idea. (If you capture a ? with a blind attack, then it should show a ? as captured - not reveal any new information that you can not already get by spending a lot of time going though the board.)
Espionage is a fun game, but I quickly learned I do not have the time to put into each game to play it with 100%. All I'm asking for is an easier way to keep track of things, and I believe most others are also.
