I compared the Gettysburg and Shiloh maps to the Talonsoft game maps, and they are very similar, except that the CWG2 maps look a lot better. The large battles such as Shiloh and Gettysburg are about 75x55 hexes, which is large enough to represent all the features of interest. Leaders Leaders play a very important role in this game. They are rated according to influence, organization, loyalty and health, and each of those numbers have a significant effect on units within their leadership radius. Division commanders temporarily replace the commander of any brigade, and influence all the brigades of their division within their command radius.
Brigade commanders influence only their own brigades.
Needless to say, leader influence encourages keeping brigades from the same division together, which makes the game more realistic. A nearby Division commander like Longstreet can turn the tide of battle. Every action of a unit reduces its effectiveness. The effective size of a unit can be significantly less than its full size. For example, a brigade with a full strength of 2000 men could be reduced to 1800 men by losses due to combat, but its effective strength due to poor organization, morale, health and experience might be only 350 men.
