I don't understand why the galactic map is still a flat 2D map. I realize we use "flat screens" and "flat panels" instead of "holotanks." BUT, why can't the galactic map be a rotatable 3D map? I saw one posting about a "corner strategy." That should be nonsense in the vast 3D immensity of a galaxy. If an enemy civilization is between me and my goal, why can't I go under or over them to get there?
