Chancellorsville was the third 'Tournament' wargame from Avalon Hill. It marked the introduction of hex based maps to the hobby (contemporaneously with D-Day and Gettysburg) It also marked an unfortunate experiment in early wargame map graphics -- instead of using illustrations to depict terrain features, the hexes were simply filled with a single color. The result was more mosaic than map.After a couple of years, Chancellorsville was dropped from the Avalon Hill line. In 1974, Avalon Hill released Randall Reed's revision of the game. However, by the mid 1980's Chancellorsville had vanished from the Avalon Hill catalog. - BoardGameGeek
