Sid Meier's Gettysburg!Sid Meier's Gettysburg!

Sid Meier's Gettysburg! is a real-time tactical computer game designed by Sid Meier, the co-founder of Firaxis Games, that was released in 1997 by Electronic Arts. In 1998, Gettysburg won the Origins Award for Best Strategy Computer Game of 1997. It was followed by Sid Meier's Antietam! in 1998.

The game allows the player to control either the Confederate or Union troops during the Battle of Gettysburg in the American Civil War. It can be played as single scenarios, or as a campaign of linked scenarios, either recounting the original history or exploring alternative possibilities.

The engine was also used for the Napoleonic game Waterloo: Napoleon's Last Battle (as was a modified version for Austerlitz: Napoleon's Greatest Victory), both by BreakAway Games.
