This third printing of the award-winning initial game in GMT's GBACW series offers upgraded components and information throughout. If you own the original 1995 edition of Three Days of Gettysburg, or if you have the upgrade kit, you can continue playing those versions with no problems; those versions still stand the test of time quite well. In this Special 2004 Edition of Three Days of Gettysburg, we've done our best to improve and enhance the components and rules to this already classic game.
