Sid Meier's Gettysburg!

Sid Meier's Gettysburg! is a real-time tactics 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 a single scenario, or as a campaign of linked scenarios, either recounting the original history or exploring alternate 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.

Mods
Gettysburg had a large modification ("mod") community. Players can customize uniforms, maps, sounds, and units. This aspect of tweaking the game proved vital to Civil War aficionados looking for historically accurate models. This ultimately led to the creation of other famous battles such as the Battle of Fredericksburg, the Siege of Petersburg, and more.

Online play
There was a large online following when the game was being hosted on Mplayer (a multi-player game network bought by GameSpy industries). Since moving to GameSpy the game has dwindled in popularity for online players; however a few players can still be challenged to online play at the GameSpy lobby.

The WarZone is now becoming the place to play Gettysburg! online. It can currently be played in the Other Games lobby.

At the pinnacle of online play there were many groups (aka clans) of players. A competitive ladder (league) was also a fixture of this time, where the hall of fame can still be viewed. "Case's Ladder"

There is also a newly re-activated Case's MyLeague Ladder at http://www.myleague.com/getty
