One that could fit the bill is an early Napoleonic wargame, I think simply called “Austerlitz”, even though I could be mistaken, from I guess the late 80s, maybe early 90s.
It had some realistic features that I liked and never found again in any other wargame :
-You were seeing of the battlefield only what your character (Napoleon on the French side, for instance) could see from where he was. Better pick a good vantage point (and not having your headquarters routed, as happened to me once). This one isn’t necessarily unique, though.
-The only other source of information were written messages from your subordinate commanders. That could be more or less reliable, and, since it took time for the messages to reach you, informed you about the situation as it was earlier, not right now. They typically included pleas for reinforcements immediately needed.
-Your orders were also in the form of messages. That would take time to reach the frontline, so you couldn’t expect your units to react immediately, nor could be sure that the orders would still be appropriate when delivered. Assuming that they were delivered at all, since the messenger himself could be killed on the way, for instance.
-Your commanders didn’t necessarily actually obey your orders, or obey them fully (say they launched a short and timid attack when you ordered a full on assault), supposedly according to their historical personality. For instance Murat was prone to launch cavalry charges, whether you wanted him to or not. Could be useful if appropriate in a changing situation, or disastrous.
I understand how these interesting and realistic features haven’t been favored. They mean that the player has only limited information and a limited control on what’s going on, and can very well lose simply because a general failed to execute his orders, or because a report he received was mistaken. Still, that was an interesting take on tactical wargames, and I wish there would be some others like that.
