In all seriousness, while I appreciate the realism, I can't help but feel having a good map would have been more preferable. I mean it's not like Lee saw little bugle horns moving around his map as Longstreet made his attack on the Union left flank, so we already got away from historical accuracy with that one. And I think the biggest problem with the map is that the units blend into the terrain to the point it's almost impossible to get any situational awareness from the map at all.
This is one area I'd be willing to sacrifice historic accuracy (as far as the date of the map) to have a map that is more detailed, such as the Warren map that was posted in a link in another thread. That map showing the fences, town, topography, woods, orchards, roads, streams, and farm names would be an excellent candidate even though it was made a couple years after the battle. It could be broken up into the four game maps. While it may not match the game perfectly as far as things like fences or orchards, etc. it seems it should be more than adequate for it's purpose. I agree that it does have to be zoomable (and therefore scrollable) to adequately interpret the tactical situation when things get crowded. Could the unit symbols on the map be designed to show facings?
