"Gettysburg: High Tide of the Confederacy" is a brigade-level wargame simulation of the American Civil War battle of Gettysburg, fought from July 1 to July 3, 1863, between Union and Confederate forces. The game is suitable for two to eight players. With two players, one takes on the role of General Robert E. Lee, commander of the Confederate Army of Northern Virginia, while the other player assumes the role of General George C. Meade, commander of the Union Army of the Potomac. With more players, each assumes command of one or more corps. According to the publisher, the game is most enjoyable with between four and six players. While not overly simple, the game is not complex, and experienced wargamers will have little difficulty with the mechanics of play. There are six scenarios, including a campaign scenario that simulates all three days of the battle. The publisher suggests that the four-turn "Assault on the Round Tops" scenario be played first in order to become familiar with the game turn sequence and the line-of-sight rules. Depending on the scenario selected, playing time is between 2 and 18 hours.
