G63 Gettysburg 1863 Board Game

G63 Gettysburg 1863 is a hex-and-counter board game of the battle of Gettysburg. The print-and-play game is free for the downloading. I am not sure, however, if it is entirely serious in nature. There are just two counters and the board has just seven hexes. The rules, however, seem to indicate something more serious. Strange.
