If you want to use the poker comparison you only don't get to see when they choose not to show you. Granted this is the majority of the time, the standard practice if you will, but you can show your cards if you want. Could be likened to choosing to disband your units as you mentioned to "hide your hand", then all you would see would be any cities, in whatever state.
The history with stats doesn't get to the point because pure numbers are very misleading in both directions.
I guess I wasn't thinking so much of the tactical advantage of seeing tactics, with a turn by turn replay, as opposed to a snapshot of the final turn or so to see if I crushed my opponent or barely won. Can't speak for the the OP. I know he talked about how things progressed throughout the game, I just want to see how it looked at the end. More a satisfying of curiosity than trying to steal tactics. Granted if that is the side effect of showing any of your opponents holdings at the end, then point taken.
